无产阶级文化大革命以来,从事红外技术工作的工人、科技人员由于深入批判了刘少奇、林彪、四人帮的反革命修正主义路线,使我国红外事业得到了很大发展。近几年来,许多单位又开展了热电探测器的研究工作。由于这种器件在室温工作,比光子探测器有更宽广的光谱响应和响应速度怏的特点, Since the Great Proletarian Cultural Revolution, workers, scientists and technicians engaged in infrared technology work have greatly developed the infrared industry in our country because of their in-depth criticism of the counterrevolutionary revisionist line of Liu Shaoqi, Lin Biao and the Gang of Four. In recent years, many units have conducted research work on pyroelectric detectors. Due to the fact that this device operates at room temperature and has a broader spectral response and response speed than photon detectors,
