| Abstract: | the design methods on drive circuit and analog output digitization of 384×288 uncooled infrared focal plane UL03162 were presented, the impact of the bias voltage on the focal plane device performance were discussed in theory and practice, the bias voltage generation programs were clarified, and methods of the timing control generation and selecting converter were described in brief. It provided the necessary conditions on working high-performance stably and reliably for focal plane. Through measuring using the test system, RMS noise is 312.4 μV, the superior performance of the device had been performed. |
