Abstract

In this paper, on the base of simple introduction of inner structure of 320×240 pixels UFPA in electronics and calorifics, the relationship of NETD (noise equivalent temperature difference) and bias voltage are researched and presented through the formulas about noise and NETD. The relation between NETD and four kinds of temperatures is presented. Moreover the two bias voltages are adjusted to observe the changing of NETD. Some experiments on power consumption and image quality of thermal imaging system is done, the result data is given. On the basis of the theory and experiments, how to enhance the NETD performance of UFPA (Focal Plane Array) at much lower or higher than room temperature is researched by analyzing experiment data. At last, the conclusion is summarized: in order to get the best image and the lest power consumption, we should adjust these parameters to find the optimized configuration at different application conditions.
