| Notes | Thermal characteristics of new substrate-free FPA （focal plane array） with full hollow supporting frame struc- ture are very different from that of traditional substrate FPA. The thermal analysis model which based on temperature- constant substrate assumption is not efficient any more. Therefore, an equivalent circuit model was presented to analyze the thermal response characteristics of substrate-free FPA with electrics and holistic approach. According to this model, the thermal characteristics of substrate-free FPA under non-vacuum environment were analyzed. The result shows that, the substrate-free FPA has excellent infrared imaging performances under atmospheric pressure, while its NETD （noise equivalent temperature difference） is just increased several times than in the vacuum environment. 31-1577/TN ZHANG Yong, CHENG Teng ZHANG Qing-Chuan CHEN Da-Peng GAO Jie, MAO Liang , WU Jian-Xiong , GAO Yue （ 1.
