Figure 2: 1948 Gabor poster Figure 1: Gabor patent illustrations, Dec 1947. FIG.1: Illustration of source point S, rays diffracted at object point O, and resulting interference with undeviated rays at point P. The hologram is the pattern of such interference points at surface 1. FIG.2: Appearance of interference pattern produced by the diverging beam and ‘punctiform object’ (i.e. opaque spot O). FIG.3: Diagram of the electron-beam portion (i.e. first half) of the holoscope, which employs three electromagnetic lenses to produce a divergent beam diffracted by the object at O. FIG.4: Diagram of the optical reconstruction portion (i.e. second half) of the holoscope, which Gabor dubbed a ‘synthetizer’ (sic). The hologram | yields a reconstructed image visible in microscope eyepiece 15. Figure 3: Gabor in middle age
