用微弱信号检测技术研究光电阴极

Research on Photocathode with Weak Signal Detection.

本文概括介绍了用微弱信号检测技术研究光电阴极的光吸收、组分、电子亲和势、折射率、衰减率和透射率等.并提出用微弱信号检测技术可以改进多碱光电阴极的制备工艺和性能。探索Ⅲ—Ⅴ族负电子亲和势光阴极的蒸发方法,从而降低Ⅲ代夜视器件的成本.

The present paper introduces briefly the research on photoabsorption,composition,electron affinity,refractive index,extinction coefficient and transmissivity of photocathode with weak signal detection(WSD).It is stated that WSD can be used to improve technological processes and properties of multialkali photocathode,to study evaporation techniques for Ⅲ—Ⅴ negative electron affinity,thus reducing the cost of Ⅲ optical imaging devices at low light levels.
