Highly sensitive camera tube using avalanche multiplication in an amorphous selenium photoconductive target

摘要: A study has been made of a very sensitive camera tube especially suitable for HDTV. It was found that an experimental with photoconductive target amorphous selenium exhibits high sensitivity quantum efficiency greatly in excess unity at applied electric field the order i08 V/rn. This phenomenon results from avalanche multiplication target. The which 2 m thick about 10 times as great conventional tube. can be increased still further by using thicker Deterioration lag and resolution characteristics caused not observed. avalanche-mode also exploited HDTV serious problem lack cameras solved dramatically. 1.© (1992) COPYRIGHT SPIE--The International Society Optical Engineering.
