Abstract

Abstract

After thorough studies on the sensing principle, the tolerance for aberration and the spectrum quality, a simplified and integrated optical readout technology has been put forward and developed, to realize the miniaturization, integration and lightweight of the optical readout focal plane array(FPA) infrared imaging system. First, based on the thermal-mechanical effect of FPA, the working principle of optical readout FPA infrared imaging system is introduced. Secondly, in view of the large size, heavy weight and complicated structure of the conventional system, a novel optical readout system with the characteristics of high integration is presented. Then, after analyzing and discussing the aberration tolerance of optical readout infrared FPA imaging system, the optical readout system containing a special-shaped prism is simulated and designed. Finally, an optical readout infrared FPA imaging system integrated with optics, mechanics, electronics and computer technology is designed and realized. The system prototype is implemented and the experimental results indicate that the size of the optical readout infrared FPA imaging system is reduced to 175mm×83mm×105mm, on the premise of guaranteeing the image quality and sensitivity. The optical readout FPA infrared imaging system with a special-shaped prism as the core component can effectively reduce the volume, weight and power consumption of the imaging system, and promote the system's industrial application.
