电视在可见光谱中在激光制导武器发射系统和远程识别方面正日益起着重要的作用。由水蒸汽和空间微粒(灰尘和烟气)所促成的大气散射以及分子和雷利散射均能使象对比度剧烈下降,并且距离愈远下降愈烈。根据轻雾观察条件来说,对比度为80%的一个目标在距离为10公里时可降至1%。硅靶视象管,由于其耐烧伤特性,更重要的是它具有宽的频谱响应和高的量子效率,故而适于军事应用。后二种优点可以滤去较短波长,改善对比度。然而,目前工艺水平所能达
Television is playing an increasingly important role in the visible spectrum in laser-guided weapons launch systems and in remote sensing. Atmospheric scattering caused by water vapor and space particles (dust and flue gas), as well as molecular and Raleigh scattering, caused the image contrast to drop sharply and fall farther away. According to the conditions of light fog observation, a target of 80% contrast can be reduced to 1% at a distance of 10 km. Silicon target video tube, due to its burn-resistant properties, more importantly, it has a wide spectral response and high quantum efficiency, it is suitable for military applications. The latter two advantages can filter out shorter wavelengths and improve contrast. However, the current level of technology can reach
