东芝公司研制出一种高速、高分辨率的近贴式图象传感器.它是用于传真、光电复印和图象处理设备中的一种小型图象传感器件.该传感器的分辨率为16位/毫米,扫描速度为0.8毫秒/线,有效阅读长度为216毫米,这相当于A4型(8(1/2)英寸)纸的宽度.由于这种传感器的长度和原稿的宽度相同,而通常用于缩小原稿尺寸的光学透镜,要求有较长的焦距,用杆状透镜阵列成功地取代了此透镜.其焦距仅为一般透镜的十分之一.这些高速度高分辨率性能的得到,是由于采用了无定形硅发光二极管工艺、新发展起来的低噪声大规模集成电路、高密度、低噪声混合电路技术和掩膜式高分辨率光电池结构.
Toshiba has developed a high-speed, high-resolution proximity image sensor that is used in fax, photocopying and image processing equipment, a small image sensor device.The sensor resolution of 16 / Mm with a scan speed of 0.8 ms / line and an effective read length of 216 mm, which is equivalent to the width of an A4 (8 (1/2) inch) paper Since the length of this sensor is the same as the width of the original, The optical lens used to reduce the size of the original requires a longer focal length and has been successfully replaced by a rod lens array with a focal length of only one tenth of that of a typical lens.These high speed and high resolution properties are obtained, Is due to the amorphous silicon light-emitting diode technology, the newly developed low-noise LSI, high-density, low-noise hybrid circuit technology and high-resolution mask photovoltaic cell structure.
