To improve the accuracy of temperature measurement using a commercial thermal imager, the proposed correction methodology for the regression coefficients R, B, F, and O is applied, and the accuracy reaches <±1 °C in the temperature measurement range between 15 and 100 °C. The use of digital images with a Giga-Ethernet output interface for the development of temperature measurement and analysis software is the strategy of real-time temperature measurement and fast monitoring of the temperature of the target area. It will become a costeffective room-temperature thermal imager with high accuracy of temperature measurement suitable for microzone application. The use of a thermal camera for the temperature observation of a microzone on a high-power striped laser diode (LD) is advantageous in the evaluation of the heat dissipation of a submount stage to improve the output efficiency of the laser.
