title: Wavefront aberration correction analysis of an all-holographic straight-line scanner.
abstract: This paper describes an all-holographic straight-line scanner consisting only of a holographic disk and a holographic lens. Scanning beam aberration correction was extensively analyzed using diffraction theory. A new technique for simultaneously optimizing the phase transfer functions of these two holograms is proposed, and a method to construct these two holograms using holographic recording is discussed. This technique led to a compact, high resolution holographic line scanner with a 1/e(2) scanning beam spot size of 100-120 microm for a scanning width of 252 mm. The radius of the disk at the center of illumination is only 28 mm.
