Wavefront aberration analysis with a multi-order diffractive optical element

Abstract

In this paper we show an ability to use a multi-order (multi-channel) diffractive optical element for wavefront relief function expansion in terms of Zernike polynomials. This approach can be successfully used for small meanings of wavefront aberrations when the wavefront relief can be represented as a linear superposition of Zernike polynomials. Unfortunately, linear approximation is becoming unworkable with increasing of aberration meanings. In this work we study an applicability of this Zernike expansion method.

“…[84] is to use a particular phase pattern on the DMD to counteract the aberrations. Wavefront aberrations have been widely studied in the past [85], and the most common aberrations are described using Zernike polynomials [86,87].…”
