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.

随着嫦娥系列工程的实施，我国为空间物理学的发展带来了全新机遇。规划中的月球科研站、小行星探测、木星系统探测、太阳系边际探测等包含行星空间物理相关重要探测研究的项目，为空间物理学的发展提供了新的增长点。紫外光学探测在研究与生命起源、丰度及分布相关的有机成分（如碳（C）、氢（H）、氧（O）、氮（N）、水（H₂O）、一氧化碳（CO）、二氧化碳（CO₂）、二氧化硫（SO₂）等）方面发挥着关键作用，磁层与太阳边际探测同样具有重要意义。我国紫外探测技术在近地空间探测领域已发展十余年，但面对深空可变辐射环境、大探测动态范围、航天器资源受限、长服役寿命等新需求时，载荷技术仍存在明显短板，且目前尚未有公开报道。本文深入探讨了CCD成像系统的控制与噪声处理技术，搭建了完整的系统平台，研究了CCD读出控制与采集模式，并通过硬件优化与采集算法降低了系统的非均匀噪声，大幅提升了系统的测量精度。本数据集即为实际采集的实测数据。
