Abstract
Pyroelectric detection apparatus including a pyroelectric detector operative to produce an electric output in response to pulsed incident radiation and a discharge circuit for discharging the electric output. The discharge is operative to impose an effective high impedance on the pyroelectric detector during at least a portion of the duration of each radiation pulse and to impose a low effective resistance during the intervals between the radiation pulses.
