Abstract
PURPOSE:To easily produce a randomly scannable grating by one time of exposing operation with a sheet of hologram by disposing cylindrical lenses with the inclination of the generators thereof from the positions parallel or orthogonal with the plane inclusive of the optical axes of reference light and object light interfering with each other. CONSTITUTION:Light 14 which enters as a plane wave can be emitted as nearly the plane wave inclined in accordance with the cylindrical lens 13 when the generator of the cylindrical lens 13 is inclined with respect to the generator of the other cylindrical lens 12. The incident object light 3 on the cylindrical lens 12 is made into coherent collimated beams of light and in addition, the reference light 2 is also projected as the coherent collimated beams of light. The overlapped scanning line corresponding to a scanning line 7b' or 7c' is obtd. if the hologram 4 produced in such a manner is reconstructed by the collimated beams of light. The luminous flux which is the superposed scanning line corresponding to the scanning line 7b' or 7c' and converges on the prescribed curved plane is obtd. if the hologram is reconstructed by the convergent light.
