Enhancing temperature measurement accuracy of SOI diode uncooled IRFPA in shutterless operation using mathematical optimization

This study presents two investigations focused on shutterless operation and temperature measurement accuracy in an 80×60 pixel SOI diode infrared focal plane array(IRFPA). An improved shutterless correction technique was developed, allowing for the generation of a reference image from a single data acquisition in a stable environment, thus avoiding real-time updates and reducing computational load. Additionally, parameters for aberration correction were optimized using the Nelder-Mead method, achieving a temperature measurement error within 1°C for subjects between 10°C and 50°C. Ultimately, a shutterless infrared camera with high temperature accuracy was successfully created through a simple onetime correction process.
