The spectral response of broadband reflection holograms in dichromated gelatin is studied; conditions for obtaining 100-nm bandwidth and 80% diffraction efficiency holograms are given. The structure of these holograms is discussed, and the scanning electron microscope is used to investigate fringe-spacing variations.
