Thermal environment adaptability design of space-based infrared imaging system

Abstract

This study discusses the influence of temperature on infrared optical system and introduced the principle and method of non-thermal design. Based on the requirements of orbital thermal environment and technical indexes of a space-based infrared imaging system, this study conducts the thermal environment adaptability design of an imaging system. The nonthermal design of the optical system is carried out by combining active and passive methods, and thermal design and thermal analysis are carried out for the thermal environment of space orbit in which the system works. Finally, the final imaging system is validated by the thermal imaging experiment. The experimental results show that the system can eliminate the influence of temperature change on image quality in the temperature range of-20 ~ + 50 ℃, and can adapt to the thermal environment of space orbit. The imaging quality can meet the application requirements under different temperature conditions.

Design of a Communication Device of Infrared Thermal Imaging Target Recognition and Tracking System

“…Its classification principle is to separate two types of samples by adjusting the linear function parameters. When the linear function can completely separate the two types of data samples, the function equation is the optimal linear hyperplane [19]. When the data sample cannot find the corresponding linear hyperplane, the linear hyperplane with the lowest cost will be found by training the classifier.…”

“…In the same way, for the interval [ d 0 , 255], there is also such an interval that d R , s R 􏼈 􏼉 has all s i 〈 s T . en, the adaptive algorithm formula is as equation (19), where g (m, n) is the gray value of the original image pixel and f (m, n) is the enhanced gray value.…”

“…en, according to the look-up table established by formula (19), the original image is transformed into grayscale [27,28].…”
