Double-exposure recording of a lensless fourier spectrogram for forming a shear interferogram
Authors:V G Gusev
Abstract:Results of theoretical estimation of the sensitivity of a shear speckle interferometer intended for testing of wavefront aberrations are presented. It is shown that in the case of the spherical aberration the sensitivity of the interferometer is doubled to an accuracy of 12.5% for a fixed shear magnitude. Tomsk State University.
