光电数码识别和传真设备中的最主要的元件就是传感阵列。它必须有足够的传感器以便给片子上的集成提供高分辨率以及扫描机理。据报导,目前美帝的雷提康公司已经做出256个元件的自扫描摄象管的样品,并立即准备进行批量生产,现在费尔查尔德半导体公司也在研制256二极管的线性阵列。费尔查尔德公司研制的这种器件可以用矩阵型的金属—氧化物—半导体移位寄存器编码级扫描二极管阵列来实现。这种移位寄存器编码级排列成四列,这是在每一阵列的线性方向 Photoelectric digital identification and fax equipment in the most important element is the sensor array. It must have enough sensors to provide high resolution and scanning mechanism for the integration on the film. It has been reported that at present, Reidicon, the US imperial government, has made 256 self-scanning samples of phototools and is ready for mass production. Now Fairchild Semiconductor is also developing a 256-diode linear array. The device, developed by Fairchild, can be implemented with a matrix-type metal-oxide-semiconductor shift register code-level scan diode array. The shift register coding stage is arranged in four columns, which is in the linear direction of each array
