量子换能器和超高频电子学的发展,要求研究在从红外到超高频这一宽波带内辐射场的空间分布。因此当前对目视或照像记录电磁辐射的各种方法(液晶法、底片照像法、蒸汽照像法等)很重视。很多工作表明,为此目的有可能利用红外——超高频射线对已激发的光致发光体的温度效应。这种足够简单的,可直接看到红外——超高频源空间场的像的记录方
The development of quantum transducers and UHF electronics requires the study of the spatial distribution of the radiation field in the wide band from infrared to UHF. Therefore, at present, various methods of recording electromagnetic radiation by visual or photographic methods (liquid crystal method, negative film method, steam image method, etc.) are very important. Much work has shown that for this purpose it is possible to make use of the temperature effect of the infrared-ultra high frequency radiation on the excited photoluminescent body. This simple enough, you can directly see the infrared - UHF source space field of the image recording side
