AbstractLarge aperture reflection holographic optics are proposed for use in LIDAR systems to make them mechanically simpler and lighter. Aberrations are minimized using contoured fringes calculated to compensate for spherical aberrations and to reduce astigmatism and coma that results from operation off axis and at a wavelength different than the construction wavelength. Chromatic dispersion is not a problem for laser line reception and multiple line operation is possible by stacking the reflectors. A 16 inch mirror for operation at 532 has been made and delivered, methods of making the same at near IR wavelengths are discussed.
