基于单传感器的三波段共口径光学系统设计
Design of three-band co-aperture optical system based on single sensor
摘要
Abstract
The existing multi-band imaging system has the problems of large volume,high power consump-tion,and difficulty in integrating design.To address these challenges,we proposed a three-band co-aperture imaging optical system based on single sensor.First,a 1×2 multi-band lens array in the aperture stop of the optical system is designed.This array effectively captures both the visible and short-wave infrared bands sim-ultaneously in a single image plane.In addition,the imaging position deviation of the center wavelength of both bands are controlled within one pixel,resulting in dual-band fusion imaging.To address the issue of dif-ferent diffraction limits in multi-band imaging,we propose to use the joint optimization method to simultan-eously control the off-axis offset and aperture size of the split channel lens array.On the above basis,we sug-gest utilizing a dual electric diaphragm to control the switching speed of the three imaging channels.Finally,a three-band co-aperture optical system based on single sensor with a focal length of 30 mm and operating bands ranging from 480 to 900 nm,from 900 to 1700 nm,and from 480 to 1700 nm is designed.The system exhibits multiple advantages,such as excellent imaging quality,a compact structure,no moving optical ele-ments,and a rapid switching speed of the imaging band,as indicated by the design and analysis results.关键词
