The thermal time constant of the pyroelectric detector is usually determined from the cutoff frequency of its frequency response to sinusoidally modulated radiation. The method can provide reliable measurement results on condition that the thermal and electric time constants are significantly different. Literature does not give more specific suggestions of… CONTINUE READING
