Signal accumulating time control method and apparatus for a signal accumulating type radiation sensing device

摘要

In a signal accumulating time control method and apparatus for a signal accumulating type radiation sensing device which produces an electrical signal corresponding to the amount of incident radiation and accumulates the same, an accumulating time controller has first and second different control modes and is adapted to change over from one of said first and second control modes to the other when the intensity of said incident radiation fluctuates a large amount.
