Paper Abstract

Based on the spectral characteristics of the target, dual spectral imaging system is conducted in target detection. The dual spectral system has simultaneously less false alarm probability and widened operating distance, There are many models of dual spectral system, such as ultraviolet and visible light, visible light and near infrared, mid-IR and long-IR system and etc. The principle of dual spectral system is described, and especially the paper studied deeply hybrid refractive-reflective dual-band system; refractive mid-IR and long-IR system. A designed sample of part-optics-light-path refractive detection system based on the application of re-imaging and 100% cold shield efficiency is given which is operating in the 3.7~4.8μm and 7.7~10.3μm wavelength bands and the rectification of the ray aberrations in both bands has been simultaneously accomplished. Because of the same aperture, field of view and focal length, the dual spectral optical images can be coupled and be simultaneously displayed in one picture.
