Sample manuscript for an optical readout infrared imaging system based on polarization to eliminate stray light

摘要

In the optical readout uncooled infrared imaging technology, the stray light produced by the reflection of the optical component surfaces is acquired together with the effective signal light by the charge coupled device (CCD, the dynamic range of CCD is limited), which reduces the dynamic range of the effective signal light. In this paper, we present a polarized optical readout system to eliminate the stray light. Shading experiments show that, in the new system, the stray light is filtered out up to 86% and the dynamic range of the effective signal light significantly increase by 50%. Infrared Imaging experiments show that the noise equipment temperature difference value decreases by 35%, and the infrared imaging performance is greatly improved.
