基于长波576×6扫描型热像仪的改进设计

摘要

通过对长波576×6扫描型热像仪的扫描器组件摆扫频率、探测器配置、AD采样速率、信号处理速度以及图像数据的隔行和插值处理等的改进,提高热像仪的帧频至25 Hz,使之转为标准热像仪,以满足一般红外跟踪观察系统的要求.%Important factors of the scanning thermal imager based on 576 x 6 long-wavelength infrared detector are improved. The factors are. The sweeping frequency of the scanner component,the configuration of the detector,the speed of the AD sampling and the processing method of the image data. All of these contribute to enhance the imager's frame rate to 25 Hz and make it to be a standard video thermal imager used in general infrared tracking and monitoring system.
