Abstract

Complex wavefront manipulation is a promising technique for many applications of optics and photonics. In this report we will present our results on development of DMD wavefront correction experimental setup and discussion of its performance for various parameters of binary fringe pattern and 1^st diffraction order filtration aperture. It was shown that trade-off between spatial resolution and discretisation of the desired amplitude and phase distribution should be achieved. Decrease of the binarized interference fringes width results in higher spatial resolution of the modulated complex wave but increase discretisation of amplitude and phase distributions as well. The correction of wavefront aberrations using digital micromirror device was performed. We observed significant reduction in wavefront phase error by conduction of Zernike polynomials decomposition.
