摘要： A technique for producing pixel patterns at different selected wavelengths. A diode laser is repeatedly pulsed and has its temperature changed from pulse to pulse, which causes the output wavelength to change. This allows pixel patterns to be interlaced by the use of dispersive elements such as prisms in the optical train. A temperature shift of about 15.degree. C. provides a wavelength shift of about 30 angstroms, which is usable. A temperature shift of 20.degree. C.-30.degree. C. or more is preferable. The temperature shifts may be accomplished by supplying specific currents below threshold and above threshold. For two-wavelength operation, the laser is driven at a first bias current below threshold for a first non-illumination interval, at a first pulse current above threshold for a first illumination interval, at a second bias current below threshold for a second non-illumination interval, and a second pulse current above threshold for a second illumination interval. The bias currents are sufficiently different so as to establish different operating temperatures for the illumination intervals. The temperature shifts may also be accomplished at least in part by use of an auxiliary heater.
摘要翻译：用于产生不同选定波长的像素图案的技术。二极管激光器被反复脉冲并且其温度从脉冲变为脉冲，这导致输出波长改变。这允许像素图案通过使用诸如光学列中的棱镜的色散元件来隔行扫描。约15℃的温度偏移提供约30埃的波长位移，这是可用的。温度变化优选为20℃-30℃以上。温度漂移可以通过提供低于阈值和高于阈值的特定电流来实现。对于双波长操作，对于第一非照明间隔，激光器以低于第一非照明间隔的第一偏置电流被驱动，在第一照明间隔的第一脉冲电流高于阈值时，在第二非 - 照明间隔和第二脉冲电流高于第二照明间隔的阈值。偏置电流充分不同，从而为照明间隔建立不同的工作温度。至少部分地通过使用辅助加热器也可以实现温度漂移。

摘要： An optical image bar utilizing polarized light and a coherent spatial light modulator, includes birefrigent spatial or angular shearing means for uniformly dividing the spatially modulated radiation of a coherent image bar into a pair of laterally offset, redundantly modulated, orthogonally polarized optical field distributions. Imaging optics, which include any spatial filtering and/or polarization filtering elements needed for converting those field distributions into correspondingly modulated spatial intensity distributions, bring the filtered field distributions to focus on an output image plane, thereby producing redundantly modulated, laterally offset, intensity profiles on the output image plane which spatially sum with each other on an intensity basis. The magnitude of the shear is selected so that the image plane offset of those intensity profiles is approximately equal to one half of the nominal image plane pixel pitch of the image bar, whereby each of the intensity profiles redundantly overwrites the interpixel intensity nulls of the other. Spatial shearing is preferred for image bars having telecentric imaging optics, but angular shearing is a practical alternative for some embodiments.

摘要： An electro-optic line printer comprises a recording medium, a multigate line modulator for printing picture elements or pixels in spatially predetermined positions along a printing axis and an LED side-facet source characterized by having high output intensity and a uniform far field emission and optical means to collimate the far field emission in the tangential direction and focus the near field in the sagittal direction onto the modulator. The optical means comprises a first lens system to collect the light emitted from the LED source in both the tangential and sagittal directions and a second toric lens to collimate the light into a sheetlike beam in the tangential direction and to focus the light in the sagittal direction to a line image at the modulator. Imaging means is optically aligned between the modulator and the recording medium for imaging the modulator onto the recording medium. The solid state LED side-facet emitter source with broad uniform far field emission and high brightness density for line printer applications, eliminating the necessity for an array of individually addressable LEDs required as a light source in the past. Deposited on one facet of the LED source is an AR coating (single or multilayer) with an index of refraction chosen to be approximately midway between the effective modal refractive index of the source and the refractive index of air.

摘要： A light source comprises a semiconductor laser having a plurality of deposited semiconductor layers including an active region consisting of a plurality of layers forming at least two quantum wells in the active region. The layers immediately adjacent to the active region provide confinement for light generated in one or more optical cavities established in the active region and propagating between end facets of the source. Means, such as in the form of an antireflection (AR) coating, is provided to convert the semiconductor laser into a superluminescent LED source. Further, means is provided to broaden the wavelength spectral emission from the source by rendering the energy levels present in the quantum wells to be at different levels between or among the quantum wells. The resulting output beam has high output intensity and a uniform far field pattern without intensity variation along the beam width particularly useful as a superluminescent LED source for electrooptic line TIR modulators and line printers.

摘要： The present invention is directed to a driving method for compensating the response speed change of an electrophoretic display due to temperature variation, photo-degradation or aging of the display device, without a complex structure (e.g., use of sensors). This is accomplished by combining two waveforms, one of which causes the grey level to become dimmer and the other waveform causes the grey level to become brighter, as the response speed degrades.

摘要： A method and mechanism for ensuring quality control in printed biological assays is provided. A multi-ejector system having a plurality of individual drop ejectors is loaded with a variety of biofluids. Biofluids include at least a carrier fluid, a biological material to be used in the testing, and markers, such as fluorescent dyes. Data regarding the biofluid loaded in each of the drop ejectors is stored along with an expected signature output of the biofluid. Particularly, the signature output represents signals from individual ones of the fluorescent markers included within the biofluid. Once a biological assay consisting of the biofluid drops has been printed, a scanner capable of detecting the markers scans the biological assay and obtains signature output signals for each of the drops of the biological assay. A comparing operation is undertaken to compare the obtained signature output through the scanning operation, with the expected signature output signals for the biofluid loaded in the corresponding drop ejector. The biological material itself may also be tagged with a marker to ensure its inclusion in the biofluid. By the comparing operation, it is possible to verify the biofluids were loaded in the proper drop ejector, including the proper biological material, and that the drop ejectors are functioning properly.
