Paper Abstract

The possibility of application of a holographic lens for Fourier spectrum analysis is discussed. A set of parameters describing a holo-lens, including location of its input pupil and curvature of its surface, are proposed according to the results of III order aberration analysis. Recording holo-lens on spherical surface creates the possibility of coma correction. The assumption that the input pupil is not in contact with the lens (as it is the case of Fourier transforming setup) enables change in astigmatism, field curvature, and distortion; the latter being very important for the lens used in Fourier spectrum analysis. The imaging quality of the proposed lens was investigated numerically by evaluating aberration spots for different spatial frequency components.
