基于大面阵铟镓砷探测器的短波红外光学系统设计
Optical Design of Shortwave Infrared System Based on Large-Area Array Indium Gallium Arsenic Detector
摘要
Abstract
In recent years,with the rapid development of indium gallium arsenide(InGaAs)detectors,shortwave infrared(SWIR)technology has demonstrated unique advantages in fog penetration and night-time detection,leading to widespread applications in night navigation,assisted driving,military reconnaissance,and other fields.The introduction of 1280×1024 pixel InGaAs detectors in China has underscored the growing importance of developing SWIR optical systems with large-area arrays and large relative apertures.To address the demands of night vision imaging in complex environments,this study presents the design of a SWIR optical imaging system based on a 1280×1024 pixel InGaAs detector with a 15 μm pixel pitch.The system enables high-resolution,wide-field imaging and is built upon a classical double Gaussian optical configuration.By employing a carefully selected combination of commonly used visible-light optical materials,the design achieves apochromatic correction across the SWIR band.The resulting optical system offers key advantages,including compact size,large relative aperture,high resolution,and excellent manufacturability.关键词
