靶场偏振成像技术应用

Application of Polarization Imaging Technology in Instrumentation Ranges

偏振成像技术不仅能获取目标的辐射强度信息,还能获取到偏振信息,有助于复杂环境下目标的探测识别。靶场现有光电设备主要采用强度探测,通过目标—环境差别来区分目标,因此,在复杂环境下,目标容易湮没在背景中难以探测。通过分析偏振成像原理和技术特点,总结归纳国外在偏振成像方面的试验应用,阐述了偏振成像在靶场应用的前景和优势,提出了一种基于偏振成像的光学成像系统,并对现有设备提出了偏振化改造方案。通过利用目标、环境的偏振特性,利用强度+偏振的组合模式,可提升现有设备的目标探测和成像识别能力。最后,对偏振技术应用和发展进行了展望。

Polarization imaging technology can obtain the radiation intensity of target information as well as polariza-tion information, and help detection and target recognition in complicated environment. Existing photoelectric devices mainly use intensity detection, to distinguish targets through difference between target and environment . In a complex environment, target annihilation in the background makes it hard to detect. This paper gives analysis of polarization imaging principle and technical characteristics, sums up trial application abroad, and describes the appli-cation and advantages of polarization in instrumentation ranges. A kind of optical imaging system based on polariza-tion imaging is put forward together with retrofit design of the existing equipment and polarization. Using the polari- zation characteristics of target and environment can improve target detection and image recognition ability. Finally, the prospect of polarization technology application and development is introduced.
