An exposure control technique based on frame transfer CCD is proposed to greatly improve the dynamic range in hyperspectral image detection. It adopts a new working mode of integrating first and then reading out, combined with the fast charge dumping timing control method of chargecoupled devices (CCD), which can effectively remove the invalid charge in the idle period and realize fast switching between the ultrashort integration time and the long integration time exposure period. For the same detected target, the uninterruptable cycle exposure of multiple exposure cycles can be realized by fast switching between multiple integral cycles within a specified time range, so that the spectrum detection range index of this technique can be improved by more than 2 orders of magnitude compared with that of the traditional technology. At the same time, the dynamic setting mode of cyclic exposure file number and exposure time is designed. The timing simulation analysis and test verifies that the proposed design can effectively improves the adaptability of hyperspectral imaging technology in complex light environment.
