摘要： An image forming apparatus and method use interlace scanning of plural light beams by deflecting the plural beams with a rotating polygon onto a recording medium. Corrections are made to the scan envelope to compensate for errors due to perceived imperfections in the spot profile or aberrations in the optical and mechanical systems used to scan the spot. The corrections are performed by adjusting intensity of gaussian components of the envelope according to a look up table.

摘要： Microaddressable printers and other types of display systems are provided for rendering two dimensional images on high gamma, photosensitive recording media. These systems are microaddressable because they are operated in an overscanned mode to render images by scanning one or more intensity modulated scan spots over a high gamma, photosensitive recording medium in accordance with a scan pattern that causes the spot or spots to superimpose multiple discrete exposures on the recording medium on centers that are separated by a pitch distance that is significantly less than the effective spatial diameter of the scan spot or spots (e.g., the full width/half max. diameter of a gaussian scan spot). Overscanned systems have substantially linear addressability responses, so boundary scans that are intensity modulated in accordance with preselected offset values are used by these systems for spatially positioning the transitions that are contained by the images they render to a sub-pitch precision.

摘要： Substantially one-dimensional scan line images at 1200 dpi or greater are generated in response to predetermined scan line image data. A substantially uniform two-dimensional homogenous light field is modulated using a spatial light modulator in accordance with the predetermined scan line image data such that the modulated light forms a two-dimensional modulated light field. The modulated light field is then anamorphically imaged and concentrated to form the substantially one-dimensional scan line image. The spatial light modulator includes light modulating elements arranged in a two-dimensional array. The light modulating elements are disposed such that each modulating element receives an associated homogenous light portion, and is individually adjustable between an “on” modulated state and an “off” modulated state, whereby in the “on” modulated state each modulating element directs its received light portion onto a corresponding region of the anamorphic optical system, and in the “off” state blocks or diverts the light portion.

摘要： A laser scanning mechanism and multiple processing stations are circumferentially disposed around a central axis. The laser scanning mechanism includes a rotating member driven by a motor to rotate around the central axis, and an optical system fixedly mounted on the rotating member and arranged to redirect input laser beam pulses from the central axis along a circular scan path. Each station including a mechanism for moving a corresponding target object radially across the circular scan path. The laser beam pulses output from the scanning mechanism can be used to process (e.g., ablate material from) multiple target objects simultaneously. The laser scanning mechanism redirects the input laser beam pulses such that the laser beams remain on-axis and in focus as they are scanned along the circular (curved) scan path. A system for producing photovoltaic devices utilizes the laser ablation apparatus and a direct-write metallization apparatus.

摘要： A hyperacuity printing system for rendering bitmapped image data on a photosensitive recording medium, the bitmapped image data being rendered as an array of pixels across the photosensitive recording medium in a fastscan direction, and an orthogonal slowscan direction. This system includes a data source for supplying grayscale input image data and a scanning device for rendering grayscale output image data onto the recording medium. The scanning device has a device for writing scan spots on the recording medium. Further included in this system is transformation circuitry for transforming the grayscale input image data into grayscale output image data. The transformation circuitry includes a halftoner, a thresholder, and a selection device, where the selection device selects either the thresholder or the halftoner to provide the grayscale output image data. Finally, included is a modulating device coupled between the transformation circuitry and the scanning device for intensity modulating each of the scan spots in accordance with the grayscale output image data.

摘要： An apparatus and method for producing a halftone image generates halftone cells based on grayscale image data and bitmap code. A human readable pattern is embedded within the halftone image. Each of the halftone cells is formed from dot patterns having one of a plurality of predetermined shapes. The predetermined shapes of the halftone cells form the human readable pattern. The halftone cells are written onto a recording medium to produce the halftone image. Rotation of the halftone cells allows data to be encoded within each of the halftone cells without varying the tone of the image. The tone of the image may be controlled by selectively varying a thickness of the dot patterns within the halftone cells.

摘要： A printing device (10) is commanded to print a reference set of intensity values from almost white or highlight regions through almost dark or shadow regions. A measuring device (12) measures the actual outputted printer intensity levels from the printing device (10). An interpolator (14) interpolates the printer intensity levels into a best fit smooth curve plotted against the reference set of intensity levels which produces a non-linear function. A mapping means and converter (24a, 24b) calculate a set of fractional intensity values and densities which produce a linear function when mapped with the printer intensity levels. A dot area parameter calculator (28) calculates a set of dot parameters defining a configuration of a halftone dot required to fill an area within the halftone cell corresponding to each intensity level. For each position of each halftone cell, a measurement processor (30) determines a distance between a current scan position (a,b) and a nearest edge defined by the dot parameters. A gray value calculator (50) calculates a gray value for the current scan position based on the distance and angle to the nearest edge of the dot. The halftone dot is completed when a gray value is calculated for each position within the halftone cell. The gray values are stored in a look-up table (26). When a new image is to be printed, the intensity values are input (54) and the scan position is indexed (52) through all available scan positions to generate corresponding addresses in the look-up table (26), causing the corresponding gray values to be output serially in order for use by a laser diode controller (56) of a laser printer or analogous controllers in other types of printers.

摘要： In a raster output scanner, a method of switching video from one raster to the next during a scan without the creation of a visible artifact. A position encoder is used to determine the position of each raster on the photoreceptor, a first distance above the transition point and a second distance below the transition point, in the process direction. Above the first point the video will be supplied by the first raster, and below the second point the video will be supplied by the second raster. From the first point to the transition point the duty cycle will vary from 100% of data from the first raster to 50% from each raster. From the transition point to the second point the duty cycle will vary from 50% to 100% supplied by the second raster. In this way, there is a gradual, and invisible, transition from one raster to the next.

摘要： A laser recorder for recording images on a substrate in response to a video signal having a frequency which defines a pixel time (during which a single pixel is imaged) includes a duty cycle modulating digital to analog (D/A) converter which outputs a variable duty cycle high frequency signal, based upon an intensity controlling N-bit input, to a power controller which then controls the intensity of a light beam output by a laser based upon the variable duty cycle high frequency signal. The duty cycle modulating D/A converter outputs a high frequency variable duty cycle bitstream including a repeating cycle of fixed amplitude pulses, a total duration of all of the pulses in each cycle varying based upon the N-bit input signal. The high frequency of the variable duty cycle is sufficiently high so that the cycle of fixed amplitude pulses repeats multiple times within each pixel time, so that the intensity level with which pixels are formed on a substrate varies based upon the number of pulses output during each pixel time and the total duration of all pulses in each cycle. Preferably, the laser, power controller, and duty cycle modulating D/A converter are formed in a common semiconductive substrate. A detector for detecting the intensity of light output by the laser is also preferably formed in the common semiconductive substrate, and provides feedback to the power controller. In a preferred embodiment, the duty cycle modulating D/A converter varies the total duration of the fixed amplitude pulse within a cycle by varying a number of fixed amplitude, fixed width pulses output during each cycle based upon the N-bit input signal.
