Abstract
PURPOSE: To provide the method of making the patterns having high space frequencies under easy control by splitting the luminous flux from a light source of good coherence, recombining these, letting the same pass through diffusion plates and disposing a recording material in the position where the interference paterns in the luminous flux combined space create.
CONSTITUTION: Light from laser luminos flux 1 goes through a beam expander optical system 2 and a cuesta prism 3, due to which the parallel luminous flux becomes two mutually coherent luminous fluxes which then enter diffusion plates 4, 5, whereby the interference fringes are produced on the dry plate 9 coated with optical recording material 8. The diffusion plate obtained by treating the dry plate 9 by known bleaching methods is effectively used for, e.g., focusing screen incorporated into the finder optical system of cameras, screen for microviewers, screen for projectors, etc. The patterns of further higher space frequencies than the maximum space frequency of the original diffusion plate has may be created under easy control.
