Million Frames per Second Imaging Method Based on Normal CCD Sensor
An ultra-high speed imaging method based on normal CCD sensor was proposed. The light sensitive area of the chip was covered by the mask and turned into storage area.The influence of extra time that CCD charge transfer took was eliminated. So the frame rate of masked CCD could achieve million frames per second. The different types of masks were introduced, and the restoration method of masked images was discussed. The method of strip-hole array mask was used to build the ultra-high speed imaging prototype base on normal CCD, and the performance was verfied by xenon lamp. After the location of mask pixel center and mask direction are both known, the masked images is finally separated and reformed into several low resolution result images. Results show that a performance of 2 million frames per second is achieved and 14 images with a resolution of 79 pixel×79 pixel are got.
