Abstract
PURPOSE: To perform contact exposure through simultaneous exposure of plane without any intricate procedures by letting the points in the relation of face symmetry be a converging point and a diverging point and letting convergent spherical waves interfere with respect to the photosensitive plane of a photoreceptor then recording the interference fringes on a photosensitive face.
CONSTITUTION: For example, a laser is used and the luminous fluxes bisected by a semi-transparent mirror are converted to a divergent spherical wave 8 and a convergent spherical wave 6 respectively by lenses, etc. The luminous fluxes of the convergent spherical wave 6 and divergent spherical wave 8 have nearly equal incident angles at an arbitrary point of a photoreceptor 1 because the convergent point 5 and divergent point 7 are so disposed as to assume nearly face symmetry with respect to the photoreceptor 1. If the incident angle of the divergent spherical wave at an arbitrary point on the photoreceptor is let to be θO and the incident angle of the convergent spherical wave to be θR, then the phase difference of the two luminous fluxes become θR=-θO. Hence, the phase difference becomes formula [I] and the interference fringes which are constant in the thickness direction of the photoreceptor are recorded and therefore contact exposure may be accomplished through simultaneous exposure in plane wave.
