Data collection of CCD system for deep space spectral imaging detection

With the implementation of the Chang 'e series program, China has also brought new opportunities for the development of space physics. The planned lunar scientific research station, asteroid exploration, Jupiter system exploration, solar system edge exploration, etc., including important exploration and research related to planetary space physics, provide a new growth point for the development of space physics. Ultraviolet optical exploration has played an important role in studying organic elements related to the origin, abundance and distribution of life, such as C, h, O, N, H2O Co, CO2, SO2, etc. Magnetosphere and solar marginal exploration play a very important role. China's ultraviolet detection technology has developed for more than 10 years in the field of near-earth space detection. However, the payload technology is very weak in response to the new requirements such as the variable radiation environment in deep space, large detection dynamic range, limited aircraft resources, and long service life, and has not been reported publicly so far. In this paper, the control and noise processing of CCD imaging system are deeply discussed, the whole system is constructed, the control and acquisition mode of CCD readout are explored, and the non-uniform noise of the system is reduced by hardware and acquisition algorithm, and the measurement accuracy of the system is greatly improved. This dataset is the actual data collected.
