焦平面热成像图像显示电路设计

Design of a Thermal-imaging System for Showing Circuits of the IR Focal Plane Array

本文介绍了基于CD22402电视同步信号产生器和DAC8308的弹用焦平面图像显示电路的设计。首先研究了原理和设计要求,然后对各部分硬件设计进行了详细介绍,最后介绍了电路的调试。实验结果表明:能完成把经过校准后的数字图像灰度数据和图像处理中形成的信号转换成模拟视频信号,并将系统时序转换成电视时序功能。

This paper presents the design for showing circuits of the IRFPA of the IR thermal-imaging on sync generator for TV applications and video processing systems and DAC8308. It firstly studies the working principle and requirement of the thermal-imaging system, then it gives the hardware structure of the system in details, the last part introduces the test of the system. The results of the experiment have indicated, the showing circuit can successfully achieve converting the datum and signals corrected gay level images to analog video signals and the time series of the system to the TV＇s.
