本发明介绍热象仪系统。在热象仪中,发射红外辐射的场景通过光学扫描器连续扫描,投射给探测器,其输出信号波形由信号处理线路馈给视频输出装置。扫描器进行二维扫描,而探测器输出的是连续信号,它由探测器对热象仪机壳内部和景物有效扫描产生的两部分连续波形组成。因此探测器的输出信号是周期性的,周期T一般从第一次景物扫描的波形末端算起,到下一次景物扫描开始为止。景物扫描信息波形也有固定的时间T_1,热象仪的扫描
The present invention introduces a thermal imager system. In the thermal imager, the scene that emits infrared radiation is continuously scanned by an optical scanner and projected to the detector, whose output signal waveform is fed to the video output device by the signal processing circuit. The scanner performs a two-dimensional scan, and the detector outputs a continuous signal consisting of two continuous waveforms generated by the detector’s effective scanning of the interior of the thermal imager and the scene. Therefore, the output signal of the detector is periodic, and the period T is generally from the end of the waveform of the first scene scanning till the start of the next scene scanning. Scene scanning information waveform also has a fixed time T_1, thermal imager scanning
