摘要： In a color liquid crystal exposure device having a row of liquid crystal shutters, the number of control IC controlling the liquid crystal pixels of the liquid crystal shutters is reduced so as to reduce the cost. A liquid crystal exposure device for exposing a photosensitive material moving relatively includes: a color light source emitting a plurality of color lights; a liquid crystal shutter having a plurality of liquid crystal pixels arranged in a direction vertical to the relative movement direction; and a drive circuit for switching the color light emitted from the color light source and driving the plurality of liquid crystal pixels. The liquid crystal exposure device divides the plurality of liquid crystal pixels into N to form a plurality of pixel groups and arranges the plurality of liquid crystal pixels constituting the pixel groups by shifting them at a predetermined interval in a direction vertical to the relative movement direction. A drive circuit performs time division drive for each liquid crystal pixel set having a similar shift position in each pixel group.

摘要： A liquid crystal shutter, wherein three shutter rows respectively corresponding to red, green and blue are formed on one liquid crystal shutter substrate, each shutter row is formed by sandwiching liquid crystal by at least one transparent substrate on which a common electrode is formed and by another transparent substrate on which a pixel electrode and a reed electrode are formed to correspond to two pixel rows arranged in zigzag in each shutter row, and the relation between a pitch Q between shutter rows and a pitch P between two pixel rows is defined as Q=NP (N, positive integer larger than 2) .

摘要： A writing apparatus (10) for forming images from digital data onto color motion picture film or other photosensitive medium (32), the apparatus employing a single spatial light modulator (30) and having an illumination system (14) comprising a dichroic prism (26) and a plurality of light sources (20). The dichroic prism (26) directs light from each light source (20) onto a common output axis, thereby providing an incident light beam for modulation by the spatial light modulator (30). The apparatus allows high-speed imaging optimized for photosensitive media (32). Additional sensor (12) and logic components allow writing apparatus (10) to adapt to different types of photosensitive media (32) without requiring any retooling or manual adjustment.

摘要： A laser printer utilizes a total internal reflection spatial light modulator that is optimized to work with a partially coherent laser source. The laser source is a laser diode array having a plurality of multi-mode emitters. The spatial light modulator diffracts light from said laser source according to an applied electric field. A spatial filter having a slit passes designated diffracted light which corresponds to an applied electric field and the light is ultimately imaged onto an image plane by way of an imaging lens.

摘要： An optical writing printer head which can accomplish at the same time the miniaturisation and lower cost of a printer head and the assurance of the resolution of print pixels. In a printer head where an LED 2 for emitting blue light, and LED 3 for emitting green light, and an LED 4 for emitting red light are mounted on a substrate 1, the whole is covered with a cover 5, and the exposure dot sizes are restricted by apertures 6, 7, and 8 corresponding to the respective LEDs and provided in the cover 5. The sizes of the apertures depends on the colour of the light source with which each is associated.

摘要： An imaging apparatus modulates or gates pluralities of light beams through individual light valves, thereby providing a greater number and finer resolution of modulated light beams without increasing the number of light valves or decreasing the spacing between adjacent light valves. A two-step modulation process is used, the first step being performed by a light generator incorporating a polygon mirror that selectively illuminates selected bundles of fiber optic strands. One strand from each bundle is routed to illuminate one of the cells in a light valve array, such that when a bundle is illuminated, every cell is illuminated by a strand from the illuminated bundle. The second step of the modulation process involves controlling the light valve array to modulate the light beams formed by the illuminated strands at each cell. Further, by ganging together multiple light valve arrays, a composite scan line may be created which spans across the width of several scan lines generated by the individual light valve arrays. The result is finer resolution and greater imaging speed utilizing far fewer light valves.
摘要翻译： 成像装置通过各个光阀对多个光束进行调制或调制，从而在不增加光阀数量或减小相邻光阀之间的间隔的情况下提供更多数量和更精细的调制光束分辨率。 使用两步调制过程，第一步由包含多边形反射镜的光发生器执行，所述多边形镜选择性地照亮所选择的光纤束束。 来自每个束的一根绳索被路由以照亮光阀阵列中的一个单元，使得当束被照亮时，每个单元被来自照射束的线照射。 调制过程的第二步包括控制光阀阵列以调制由每个单元处的被照亮股线形成的光束。 此外，通过将多个光阀阵列组合在一起，可以创建跨越由各个光阀阵列产生的几条扫描线的宽度的复合扫描线。 结果是更精细的分辨率和更大的成像速度，利用更少的光阀。
