Fabrication of holographic optical elements for achromatic matched filtering system

Holographic optical elements such as lenses, gratings and holographic matched filters were fabricated for an achromatic matched filtering system. Diffraction efficiencies of more than 90% were obtained in all these elements. These holographic elements were used in the achromatic matched filtering system and achromatic Fourier transforms were obtained. Experimental details involved in all these methods are briefly described.
