Abstract

This paper discusses the importance of the Uncooled infrared focal plane array detector with low noise, and focuses on solving the hardware problem - how to reduce the noise of the detector by the technique of I²C and differential input. Meanwhile the hardware circuitry should meet the driving conditions. Beside of this, the author aims to describe the method using in reducing the noise of the detector driver circuit, the quantization noise of the A/D circuit, removing the image background noise, non-uniformity correction and so on. Moreover, the author analyzes the noisy level of each part of the circuitry in theory, and obtains the RMS and SNR of the practical image. The results show that: the acquisition system is working properly and has a comparably low noise performance. The RMS noise of the acquisition system is 568 μV, and the SNR reaches over 60 dB under the blackbody irradiation and the room temperature.
