Splicing structure based on three sCMOS detectors

Abstract

The invention discloses a splicing structure based on three sCMOS detectors. The three sCMOS detectors are staggered and spliced according to a delta-shaped structure; a first detector above the deltashape is used as a reference, and specifically the row pixel of the first detector is used as a Y-direction reference, and the column pixel is an X-direction reference so as to adjust the position ofthe first detector; the first detector is used as the reference, and the positions of a second detector in the x direction and the y direction at the lower left part of the delta shape are adjusted according to the splicing requirements; the first detector and the second detector are used as references, and according to the splicing requirement, the positions of a third detector in the x direction and the y direction at the right lower part of the delta shape are adjusted; and the three adjusted detectors are fixed to complete the splicing of the three sCMOS detectors. By the splicing structure, the defect that the width of the aspect of image detection is insufficient can be overcome, the field of view is greatly expanded through splicing, and a wide spectral response range, a high spectral response and ultra-low readout noise are achieved.

Description

technical field [0001] The invention relates to the technical field of detectors, in particular to a splicing structure based on three sCMOS detectors. Background technique [0002] With the development of science and technology, high-resolution satellite images are becoming more and more familiar to ordinary people and are becoming a part of people's lives. The selection of detectors and how to obtain large-format and high-frame-rate images have become urgent problems to be solved. It is directly related to the size, weight and difficulty of implementation of the camera. [0003] In the prior art, although relevant schemes for expanding the camera's field of view have been studied, there is no relevant record about the splicing of CMOS detectors that can achieve a wider spectral response range, higher spectral response, and ultra-low readout noise. In the field of aerospace, there is an increasingly significant demand for large-format and high-frame-rate image acquisition ...

[0003] In the prior art, although relevant schemes for expanding the camera's field of view have been studied, there is no relevant record about the splicing of CMOS detectors that can achieve a wider spectral response range, higher spectral response, and ultra-low readout noise. In the field of aerospace, there is an increasingly significant demand for large-format high-frame-rate image acquisition through high-performance index detectors.
