Abstract

PURPOSE: To obtain the beam scanner of large scanning angles, small aberrations and large scanning magnifications by using the hologram formed from the interference fringes obtained by causing the phase subtracted waves having been subtracted of a plurality of spherical waves and the spherical waves to interfere with each other.
CONSTITUTION: The interference fringes are formed by the interference of the phase subtracted waves having been removed of the phases of N number (N is integer) of spherical waves and the spherical waves and the interference fringes thus obtained are recorded on a recording medium, whereby a hologram is obtained. The phase distribution ϕ of the interference fringes may be expressed by formula 1. The light beam scanner using this hologram causes the light beam generated from a laser 23 to be focused by a lens 24 to be made into the divergent spherical waves which then radiate the hologram 25. The primary diffracted light from the hologram 25 focuses on a scanning plane 26 and is scanned in the direction perpendicular to the plane of the paper by a hologram moving mechanism. By using the hologram having been recorded with the interference fringes of high approximate degrees, the scanner of large scanning angles, small aberrations and large scanning magnifications may be obtained.
