摘　　要：为了定量评价量子点红外探测器焦平面阵列噪声特性，提出了一个量子点红外探测器噪声等效温差模型。该模型基于电子传输机制建立了量子点红外探测器焦平面阵列噪声等效温差模型，针对典型量子点红外探测器性能参数，定量确定了该参数下量子点红外探测器焦平面阵列噪声等效温差。通过比较模型计算和实测实验数据结果，证实了所建立的噪声等效温差模型的有效性和正确性。The development of quantum dot infrared photodetector focal plane array （QDIP PRA）, which is a central component of new type of infrared thermal imaging, has attracted more and more attention from the researchers, based on the mechanism of the electron trans- port, the model of noise equivalent temperature difference （NEAT） of QDIP focal plane array （PRA） is established, and the NEAT is calculated in quantitatively for the typical QDIP performance parameters. The validity and correctness of NEAT of QDIP PRA is verified by comparing the calculation results and with the experimental data.
