摘要

提出了基于普通CCD的掩模式成像技术来大幅提高CCD的图像获取速度，实现百万帧/秒的CCD时序驱动方法。介绍了加掩模后CCD的工作过程，利用掩模把普通CCD的光敏区划分为带有存储区的像素阵列，实现了普通CCD的片上存储功能。分析了利用普通CCD实现百万帧/秒超高帧频的时序驱动方法，掩模形状决定了帧速，帧数和图像的分辨率。对系统的时序结构、电荷转移方式和驱动电路进行了说明，通过特殊驱动电路和图像处理软件设计实现了百万帧/秒的超高帧频。最后，对驱动时序进行了仿真和实验验证。采用条状孔阵列掩模，基于普通CCD图像传感器进行了百万帧/秒工作速度的验证，获得了14幅79 pixel×79 pixel的图像，其帧频达到200×10

frame/s。文章所述技术具有一定的通用性。

Abstract

An ultra high speed CCD driver timing method based on a normal CCD image sensor was proposed to improve the CCD image acquisition speed and achieve the image speed in million frame per second. The working processing of the CCD after masking was introduced. With a specialized mask

the original light sensitive area of the normal CCD sensor was divided into pixel array with a certain storage area to implement the storage function on a chip. The driver timing method to achieve the image speed in million frame per second was analyzed and the frame rate

frame number and resolution of the image were decided by the shape of the mask. The driver timing was well introduced

the structure of timing

charge transfer mode and the driving circuit were given

then

the ultra high speed in million frame per second was implemented by the special circuit and image processing software. Finally

The designed method and simulation result of ultra high speed logic timing were verified in detail. With a strip array mask and an ordinary CCD

the performance of 2 million frame per second is achieved

14 result images with a resolution of 79×79 are obtained. Moreover

the method proposed has universality in applications.
