研制了一种光导——场致发光型的红外象转换器。研究了把不同厚度的掺杂CdSe光导粉末层应用于象转换器的效果和工作温度的影响。其光谱灵敏区从0.7至1.2微米,峰值在0.9微米。在0℃时,对0.9微米的入射光其灵敏阈值约为2×10~(-10)瓦/厘米~2。输入的红外图象转换为可见的场致发光图象,其分辨率为每毫米3—8条电视线,根据光导层厚度和工作温度的不同,其响应时间为1—10~(-2)秒量级。用一附加的红外源,此种转换器可用作夜视仪。文中叙述了适用于光导-场致发光器件CdSe的光导体的制备,它的某些性质,以及光导体厚度和工作温度对于固体红外象转换器性能的影响。刊登了利用实验转换器得到的可见象的照片。
Developed a light guide - electroluminescent infrared image converter. The effect of different thickness of doped CdSe photoconductive powder layer on the image converter and working temperature was studied. Its spectral sensitivity ranged from 0.7 to 1.2 microns with a peak at 0.9 microns. At 0 ° C, the sensitivity threshold to 0.9 μm incident light is about 2 × 10 -10 W / cm 2. The incoming infrared image is converted to a visible, electroluminescent image with a resolution of 3-8 television lines per millimeter. Depending on the thickness of the photoconductive layer and the operating temperature, the response time is 1-10 (-2) Seconds of magnitude. With an additional infrared source, this converter can be used as night vision. The article describes the preparation of a photoconductor suitable for a light-conducting electroluminescent device CdSe, some of its properties, and the influence of photoconductor thickness and operating temperature on the performance of a solid infrared image converter. We published photograph of visible image obtained by experiment converter.
