Deviations of a fringe from straightness of the order of a tenth of its width (FWHM) can be detected in fringes of equal thickness formed between two plates. What is the smallest surface step that can be detected with a source whose wavelength is 546 nm if the reference and the test surfaces are coated so that their reflectivity R=0.9?
