摘要： A large format laser scanning system is disclosed that incorporates a compact, wobble free and wavelength insensitive scanning mechanism. The scanning mechanism includes a pentaprism and lens mounted on a rotating frame assembly that is located within a scanning drum. Multiple light beams generated by a light source are passed through the rotating pentaprism and lens to scan a photosensitive medium located on the interior surface of the scanning drum.

摘要： A three-color laser scanner using a holographically-generated plane linear grating disk (hologon). The disk includes peripherally-arranged facets having identical multiplexed diffraction gratings. Each multiplexed grating is formed from plural superimposed interference patterns accumulated by multiple exposures to light from a single monochromatic laser beam source. The multiplexed grating is optimized to diffract certain light wavelengths in a single, multichromatic (plural wavelength) input laser beam. The diffracted output beam comprises respective wavelength beam components that simultaneously scan in collinear fashion. Modulation of the plural wavelength components in the incident beam allows the output beam to scan expose a multicolor image at the image plane.

摘要： A multichannel integrated optics modulator is disclosed that generates one or more independently modulated scanning beams. The integrated optics modulator includes at least one waveguide channel provided on an electro-optic substrate, wherein the waveguide channel is divided into a write waveguide channel that extends to an output side of the substrate and a dead-end waveguide channel that terminates before reaching the output side of the substrate. Control signals are selectively applied to electrodes provided above the dead-end waveguide channel and the write waveguide channel to control the coupling of light from the write waveguide channel to the dead-end waveguide channel. Light is coupled out of the dead-end waveguide channel through the use of an absorber located above an end region of the dead-end channel. The integrated optics modulator is incorporated in a variety of scanner mechanisms.

摘要： In a laser scanner of the type having post-scanning beam shaping employing prisms between a hologon scanner and an f- THETA lens, the prisms are replaced with a planar beam expander such as a diffraction grating, thereby enabling the f- THETA lens to be positioned closer to the hologon, and therefore made smaller and hence less costly.

摘要： Moiré patterns in raster-scanned halftone dots image screens generated by multi-element line scanner devices are rendered imperceptible to the human eye by selecting the number of elements in the line scanner device to be that number which makes the ''once-around'' scanner frequency an integral multiple of the halftone dot screen frequency and makes the beat frequencies between the scanner and frequencies either fall outside the nominal visible spatial frequency range of about 2.5 to 250 lines per inch or fall on the screen frequency.

摘要： Method and apparatus for modulating the collimated output beam (62) of a laser diode (56) whose emission frequency changes with the magnitude of the current supplied to the diode. The frequency changes occur by jumps (26), in which a relatively high rate of change of frequency occurs, and by drifts (28) between jumps (26). In the drifts (28), relatively low rates of change of frequency per unit variation in magnitude of current occur. The beam (38, 58) is directed onto an interferometer (30) for converting frequency modulation to amplitude modulation. The current to the diode (56) is varied by an amount less than the current needed to cause the drift (28) between successive jumps, whereby the frequency may be shifted by drifting between a frequency at which destructive interference occurs in the interferometer (30) and another frequency at which constructive interference occurs, without causing a jump in frequency.

摘要： A scanner including a source (24) of coherent or substantially coherent light, a radial hologon (48), a f theta lens (60) and a target (64). Between the light source and the hologon there are means (32) for forming light from the source into a collimated beam having an oblong cross-sectional shape and for directing the beam onto the hologon at a predetermined incident angle and with the long axis of the oblong cross-sectional shape of the beam radial of the axis of rotation of the hologon. Prismatic means (36) are provided between the halogon and the lens means for so modifying the cross-sectional shape of the beam that the spot at the target station has a selected shape and orientation. This allows the shape, orientation and size of the beam on the hologon to be optimum for duty cycle of the hologon and for spot size on the target. The prismatic means (36) allows the spot shape and orientation on target to be optimized. The prismatic means tends to introduce undesirable bow into the scan line, therefore the wavelength of the light and the grating factor n lambda /d of the hologon are selected to produce an approximately equivalent opposite bow.

摘要： A light sensing device (10) comprises a photoconductive layer (13) overlaying an array of PN junction diodes (12) integrated within a semiconductor substrate (16). When a voltage is applied to the device (10) to reverse bias the diodes (12), the voltage divides across the device in accordance with the capacitance of capacitive elements formed by the photoconductive layer (13) and the junction capacitance of the diodes. When light impinges on the device (10), charge transfers from the photoconductive layer (13) and accumulates at the underlying junctions (17) at a rate that is directly dependent on the intensity of light incident on the corresponding portion of the photoconductive layer. When a diode reverse breakdown voltage is reached, the corresponding diode conducts. This causes an increase in current through the device (10), thereby signaling that a desired localized exposure has been attained.
