Abstract

The invention discloses a splicing method of a guide star CCD and a detection CCD of a space astronomical camera, aiming to solve the problem that the back-illuminated guide star CCD and detection CCD cannot be spliced ​​by using the traditional high-magnification tool microscope imaging method in the prior art technical issues. The present invention undergoes screening-thermal deformation verification-splicing-initial adjustment-measurement-trimming-fixation-splicing verification in sequence; the splicing method can make the splicing height and collinear error of the guide star CCD and the detection CCD meet the focal depth requirements of the space astronomical camera, and It has the characteristics of simple operation and high splicing precision.

Description

technical field [0001] The invention relates to a guide star CCD and a detection CCD, in particular to a splicing method for a space astronomical camera guide star CCD and a detection CCD. Background technique [0002] The back-illuminated CCD has the advantages of high quantum efficiency and low noise, and has gradually become the first choice for space astronomical camera CCD. In astronomical cameras, the back-illuminated guide star CCD and detection CCD are usually used, and the guide star CCD is generally The optical system is shared with the detection CCD, but the guide star CCD has high requirements for positioning accuracy for bright star imaging, while the detection CCD generally images dim targets and has high requirements for signal-to-noise ratio, so the two have different requirements for the size of the diffuse spot. The photosensitive surface generally has a fixed height difference requirement. However, the back-illuminated guide CCD and detection CCD have no ...
