Paper Abstract

This paper describes an algorithm based on the singular-value decomposition that converges to a solution for a computer-generated-hologram disperser from a random-phase starting diffuser. In this paper, we report on the application of this algorithm to the design of two-dimensional, surface-relief CGH dispersers for use in the Computed-Tomography Imaging Spectrometer (CTIS). The designed CGH's produce desired diffraction images at five wavelengths through a 1:1.67 wavelength band. Performance results are presented for a demonstration CGH designed by the SVD algorithm and fabricated in GaAs for use in the mid-wave infrared CTIS.
