1. A detector for radiation with a time-dependent amplitude, comprising:

  • a semiconductor substrate wherein said radiation is being absorbed, the radiation being absorbed in said substrate being spatially modulated such that said radiation thereby creates at least a first signal and a second signal in said detector; and

    a frequency-sensitive circuit for comparing the time behavior of said first and said second signal, to thereby define a detector output signal.
