Abstract

Measurement of a system’s transfer function by means of its response to random-noise inputs has long been a standard procedure in time-domain systems. If the input is white noise, which contains equal amounts of all frequencies, the action of the transfer function is to impart a nonuniformity of frequency content that can be assessed at the output of the system by means of a Fourier analysis. This concept has not historically been employed in the measurement of optical systems, with the exception of an initial demonstration using (non-white) film-grain noise.
