  1. A study on the characteristics of reflection spectrum of field of view under night - sky radiation

    夜天光下景物反射光譜特性的研究
  2. ( 3 ) the spectral matching factor of nea phothocathodes for reflecting spectrum of objects under night sky radiation has been studied. the spectral matching factors of typical phothocathodes, such as gaas nea photocathode, s _ ( 251 ) and s _ ( 252 ) photocathode, are calculated and compared. the factors give the explanation of high detection performance of the low - light - level night vision equipments

    ( 3 )研究了nea光電陰極和夜天光照射下景物反射輻射的光譜匹配系數,計算了gaasnea光電陰極的光譜匹配系數,並將之與s _ ( 251 ) 、 s _ ( 252 )光電陰極的計算結果作了比較,揭示了三代微光夜視儀具有優良探測性能的原因。
