Abstract

During astronomical observations, the CCD sensor will produce the smear effect during frame transfer, and the smear effect will pollute the column pixels corresponding to the image, thus affecting target detection. According to the characteristics of frame transfer CCD, the generation of smear effect is analyzed, and the gray scale analysis model of the smear effect is established, which simulates the gray value corresponding to the smear effect generated by astronomical observation cameras when detecting targets of different magnitudes and verifies it through experiments. The theoretical analysis in this paper provides an important reference for the design of astronomical cameras.
