Abstract
PURPOSE: To enable the problem of uneven diffraction efficiencies to be solved by rotating a hologram plate and duplicating recording plate about the axis which passes the center of the hologram circle and is perpendicular to the recording plane during radiation of parallel luminous fluxes of laser as duplicating light.
CONSTITUTION: A recording plate is intermittently rotated at each specified angle about the axis perpendicular to the recording plane. At each non-rotating time thereof,reference light is radiated from the direction perpendicular to the recording plane and object light is radiated from the fixed direction. The recording plate undergoes necessary processings such as developing, fixing, bleaching and other and this yields the hologram plate 1A in which the holograms of Fourier transformation type have been recorded at an equal spacing in plurality on the circumference. The plate 1A is superposed with a recording plate 1B for duplication and is rotated about the axis A which passes the center of the hologram circle and is perpendicular to the recording plane, thence parallel luminous fluxes 6 of laser are radiated. The deflection direction of the luminous fluxes 6 change relatively to the plates A, B and the changes in coherence are evened with respect to each hologram.
