A new method for evaluating the performance of holographic optical elements and holographic materials is described. The method involves recording a spherical holographic lens, aligning the lens in an interferometer, obtaining an interferogram, and analyzing the interferogram with fringe interpretation software . The analysis of the holographic lens provides a direct measure of the optical performance including the wavefront error or optical path difference, the point spread function, the MTF, and a set of Zernike polynomial coefficients. The aberration coefficients could prove to be very useful in quantifying the limiting performance of the holographic material as well as establishing a means for measuring the effects of different processes on optical performance. The ability to measure optical performance directly as well as the ability to isolate the performance of the hologram, holographic material, and hologram substrate separates this method from other techniques currently being used. The new method is named MINT (Method of INTerference).
