由于种种原因,导致了线型可见光CCD摄像器件光照时输出视频信号非均匀性的形成。非均匀性的客观存在,不仅影响了器件的使用效果,而且严重影响使用范围。如果能使那些因非均匀性而淘汰的器件“死而复生”。无疑是一件有意义的工作。本文简要讨论了非均匀性的形成,介绍了电路处理(或称补偿)方法。
Due to various reasons, the formation of the output video signal inhomogeneity is caused when the linear visible light CCD imaging device is illuminated. The non-uniformity of the objective existence, not only affects the use of the device, but also seriously affect the scope of use. If you can make those due to non-uniformity out of the device “dead and resurrected.” It is undoubtedly a meaningful job. This article briefly discusses the formation of non-uniformity, introduces the circuit processing (or compensation) method.
