系统积热对红外偏振成像系统工作性能的影响
Impact of system thermal accumulation on working performance of self-developed infrared polarization imaging system
摘要
Abstract
An in-depth investigation was conducted regarding the influence of heat accumulation in stator windings on the imaging quality of time-division infrared polarization imaging systems,leading to the pro-posal of an optimization scheme aimed at mitigating this impact.Initially,by concentrating on a self-devel-oped time-division infrared polarization imaging system,the mechanism through which heat accumulation in the stator windings results in increased infrared thermal noise,thereby compromising imaging quality,was analyzed.The structural design of the system was examined to explore the causes of heat generation in the stator windings,and a theoretical elucidation of the effects of thermal noise on imaging performance was provided.Subsequent comparative experiments were performed across a steady-state temperature range of the windings,from room temperature to post-normal operation,with an analysis of polarization characteristic images of the target scenes.The experimental results demonstrated that the infrared thermal noise induced by heating of the windings significantly undermined the imaging performance of the devel-oped infrared polarization imaging system.In the simulated sandy target scene,the structural similarity in-dex(SSIM)and peak signal-to-noise ratio(PSNR)diminished by 32.98%and 51.87%,respectively,while the mean squared error(MSE)escalated by a factor of 19.49.Ultimately,an improved design of the stator windings facilitated a reduction of 34.3%in the steady-state temperature of the rotating scanning machinery within the self-developed infrared polarization imaging system.关键词
