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.
