Abstract

Abstract

In order to realize the framing function of high-speed cameras, we proposes a high-speed camera optical system using multi-angle coupled framing methods. The framing structure uses multiple groups of the same optical system and is evenly distributed on the circumference parallel to the object plane. The same object surface is photographed from different angles. Each group is guaranteed to have the same object field of view. The angle between the optical axis of the optical system and the object plane is the same, and the best imaging of the entire field of view is obtained through optimization design. According to the requirements, a telephoto optical system in multi-angle-coupled quadrant imaging is designed using optical design software and a three-dimensional simulation model is drawn. The image quality, luminance, distortion, and other relevant parameters of each group are analyzed, and at a frequency of 50lp/mm, the modulation transfer function(MTF) is not less than 0.5, the F number is 2, and the distortion is less than 0.4%. Compared with the commonly used prism and reflective pyramidal spectroscopy, the surface illumination can be increased by more than 4 times without additional splitting structure. The results show that the imaging quality is ideal and the image formation consistency of the image planes of the framing camera system is satisfied.
