WebAug 7, 2024 · Specifying flatness is not a trivial task since you can have deviations at all spatial frequencies. For example a sinusoidal $\lambda / 10$ deviation with a period of a few dozen wavelengths makes a diffraction grating which might technically preserve wavefront flatness of each diffracted beam but wreak havoc for your application.
WebJun 28, 2024 · Since the differential wavefront-errors—i.e. a non-uniform phase profile of the interference pattern—cannot be explained by aberrations of beam feeding the interferometer, we carried out an analysis of the effect of wavefront aberrations due to the interferometer optics. In section 2, we outline the mathematical framework needed to … password jack clarkWebwavefront and direction of the incident beam; i.e. its transmitted and reflected components.
