  • Patent number: 4449045
    Abstract: A light monitoring arrangement, specifically one for monitoring relatively high frequency light pulses and producing corresponding electrical output pulses, is disclosed herein. This arrangement includes circuitry which has the tendency to become electrically saturated if the light pulses being monitored reach or exceed a certain minimum intensity level. This in turn distorts the electrical output pulses in a way which causes these pulses to merge with one another. However, the arrangement disclosed herein also includes circuitry for preventing this from occurring even if the light pulses do reach or exceed circuit saturating intensity levels.
