	'''Specific detectivity''', or '''''D*''''', for a [[photodetector]] is a [[figure of merit]] used to characterize performance, equal to the reciprocal of [[noise-equivalent power]] (NEP), normalized per square root of the sensor's area and frequency bandwidth (reciprical of its sampling rate).

	Specific detectivity is given by <math>D^=\frac{\sqrt{Af}}{NEP}</math>, where <math>A</math> is the area of the photosensitive region of the detector and <math>f</math> is the frequency bandwidth.
