Paper Abstract

We present a comparative study between two experimental methods to determine the modulation transfer function (MTF) of a hololens system. The two hololenses were previously recorded and tested for filtering pseudocolor. In the first method we used the classical Foucault test. The second, alternative method is based on the digital image processing of a perfect edge under incoherent illumination. From the digitized intensity line profiles we obtain the MTF and cutoff frequency of the optical system according to the reciprocity between line spread function and MTF. Comments are made on the applicability and accuracy of these two methods.
