自扫描光电二极管列阵(Self-Scanned Photodiocde array)是由若干个光电二极管组成的线(或面)列阵与相应的扫描电路集成于同一硅片上。形成一种特殊的光电传感器.它是属于固体图象传感器一种,和电荷耦合器件相比具有分辨高,入射光光强的动态范围大,工艺较简单,使用的外部电路简单并较易调整等优点。该类器件主要可用于光学文字(符号)识别,非接触尺寸检测,表面缺陷探测,传真,摄象等领域。 Self-Scanned Photodiocode array is a line array composed of several photodiodes integrated with the corresponding scanning circuit on the same silicon. Forming a special kind of photoelectric sensor which belongs to the solid image sensor and has the advantages of high resolving power compared with the charge-coupled device, large dynamic range of light intensity of incident light, simple process and simple and easy adjustment of the external circuit used Etc. Such devices are mainly used for optical text (symbols) identification, non-contact size detection, surface defects detection, fax, camera and other fields.
