Abstract
WE have previously described1 a method of holography with a double focus lens which, used with ‘Polaroid’ photographic material type 55P/N, provided a simple demonstration of the complete process within a total time of a few minutes from the exposure to the reconstruction from the hologram. The object used in that demonstration was a diffusely transmitting transparency. We have now adapted the same optical system to record diffusely reflecting surfaces, and have given demonstrations at the recent Symposium on Engineering Uses of Holography held at the University of Strathclyde in September 1968.
