______________ is used in the specification of optical detectors.

______________ is used in the specification of optical detectors. Correct Answer Noise equivalent power

Noise equivalent power is defined as the amount of incident optical power per unit bandwidth required to produce an output power equal to detector output noise power. Noise equivalent power is the value of incident power which gives an output SNR of unity.
