Abstract

1469397 Holography FUJI PHOTO OPTICAL CO Ltd 17 Feb 1976 [18 Feb 1975] 06157/76 Heading G2J A method, combining holography and moiretopography, of recording the surface contour and displacement of an object O Fig. 1 comprises illuminating the object O with coherent beam A through grating 20 located in front of the object O, directing the light reflected by the object to a recording material 21 through the grating 20 and illuminating the recording material 21 with a coherent reference beam B. The hologram 21 is reproduced Fig. 2 by illumination with coherent reference beam B' at an angle equal to that of B in Fig. 1 and by illumination with a coherent reproduction beam C from the opposite direction to B'.
