基于阵列光学的快速多维度成像制导光学系统设计
Design of a fast multi-dimensional imaging guidance optical system based on array optics
摘要
Abstract
To address the bottleneck that makes the conventional polarization spectral imaging method diffi-cult to apply to the ballistic platform,a fast multi-dimensional imaging guidance optical system based on ar-ray optics is proposed.The correlation model between channel resolution and telescopic magnification is con-structed.The precise matching and efficient utilization of the parameters of the microlens array,spectral fil-ter array,and micro-nano-polarization array detector are realized.Based on the conventional guidance head and commercial polarization detector,a multi-dimensional imaging guidance optical system with spherical dome is designed.The system adopts a 4x4 optical field segmentation layout,forming 16 spectral channels through the visible light band with a spectral resolution of 16 nm.A polarization spectral data cube in four polarization directions,such as 0°,45°,90°,and 135° is acquired efficiently under the conditions of a single optical path and a single detector.The system has an effective focal length of 150 mm and a structure length of 145 mm.Simulation results show that the full-field modulation transfer function of the system is close to the diffraction limit at the Nyquist frequency for 16 channels.The imaging quality meets the requirements of bullet-loaded target multi-dimensional detection and identification.关键词
