摘　　要：综述了热释电摄象管红外热电视的三种调制方式（平移、斩波、回转跟踪）的特点，并论述了回转成象及跟踪原理，着重对跟踪精度作了分析讨论，指出在设计和调整跟踪电路时减小幅度和相位误差的重要性，最后对一种实用的集成化跟踪电路作了简介。Beginning with the summarization on panning,chopping and rotating-tracing modes of the infrared televi- sion using the pyroelectric vidicon,the principle of imaging by the rotating optical device and imaging tracing are discussed in the paper. The precision of imaging tracing is analyzed in particular,The importance of mini- mizing amplitude and phase errors in designing and debugging tracing circuit is pointed out.Finally,the trac- ing circuit is briefly described.
