Description

technical field [0001] The invention relates to the field of research and development of a space high-speed TDICCD camera electronics system, in particular to an image acquisition and display device for a high-speed TDICCD remote sensing camera. Background technique [0002] Time-delay-integrated charge-coupled device (TDICCD) is a new type of CCD image sensor with an area array structure and line array output. It uses a multi-row line array photosensitive array to repeatedly expose the same target multiple times, and accumulates the exposure induction signals. Therefore, the detection sensitivity and imaging signal-to-noise ratio are improved without affecting the pixel output rate and ground resolution. In space-to-earth remote sensing imaging applications, the advantage of TDICCD is used, and a small relative aperture optical system is used to achieve higher resolution, thereby achieving high resolution and miniaturization of the space remote sensing camera system. Theref...
