引言相比于可见光、红外波段和微波,电磁波谱中亚毫米波段直到最近应用尚少.其原因之一,是20μm至1mm波段范围内缺乏有效的功率源.但是,目前由于种类繁多的激光器出现,改变了这种情况.这就为成象展示了可能的应用前景,主要用于绘制激光模式图形,但也可用于雷达模拟和隐蔽目标的探测.热电摄象管——具有测热辐射功能的 Introduction One of the reasons that the sub-millimeter-wave band in the electromagnetic spectrum has been less widely used than the visible, infrared and microwave ranges is the lack of an effective power source in the 20 μm to 1 mm band, however, due to the wide variety of lasers available today , Which changed the situation.This shows the possible application of the imaging prospects, mainly for drawing the laser mode graphics, but also can be used for radar simulation and detection of covert targets.Photoelectric tube - with the function of heat radiation of
