ABSTRACT:
Apparatus for piecewise generation of grating-like patterns in photoresponsive material with a coherent the class which splits the coherent beam into two component beams. The two component beams intersect forming a parallel plane interference pattern on a section of the photoresponsive material. An arrangement which translates the beam parallel to itself forms the interference pattern in registration with the previously generated pattern on a different section of the photoresponsive material.
