Abstract

A new data acquisition scheme is presented which produces interferograms with constant standard deviations from shot-noise-limited signals. This is accomplished by tuning the frequency response of the data acquisition system in real time in response to the noise in the interferogram. A constant amount of shot noise is recorded with each datum, regardless of signal intensity, so that the multiplex disadvantage is nullified for these data.
