Problems solved by technology

[0005] The current mainstream splicing optical imaging system mainly uses a single PBS prism (polarization beam splitter) and a micro-display chip for imaging. Due to the imperfection of optical components and the secondary reflection inside a single PBS prism, the existing Although this type of splicing optical

Abstract

The present invention provides a spliced ​​optical imaging system, which comprises: a first display group (100) with a first micro-display chip arranged along a first optical path; a second display group (100) with a second micro-display chip arranged along a second optical path; A display group (101) and a polarization combination module (102) located at the intersection of the first optical path and the second optical path, the first optical path and the second optical path are perpendicular to each other, and the first display group The image displayed by (100) and the image displayed by the second display group (101) are imaged on the same imaging plane after passing through the polarization combining module (102). The splicing optical imaging system can effectively realize the seamless splicing of confocal planes and other frames, can meet the use requirements of larger arrays, and has higher splicing accuracy and contrast.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a spliced ​​optical imaging system applied to a dynamic star simulator. Background technique [0002] With the gradual development and improvement of the aerospace field and the improvement of ground supporting detection and calibration equipment technology, the dynamic star simulator is used as a calibration inspection equipment for simulating starry sky images in this type of equipment, and its accuracy and resolution are also developing day by day. . [0003] The stitching high-resolution optical imaging system is the core display module in the dynamic star simulator, and its stitching accuracy, resolution and contrast directly determine the performance of the dynamic star simulator. [0004] Due to the production and processing limitations of micro-display devices such as TFT-LCD, DMD, and LCOS in the field of micro-displays, it is difficult to produce large-scale, high-res...
