Is Split-Beam Holography Even Necessary?
Just as with a single-beam reflection hologram, “direct” split-beam reflection holograms do not exhibit any of the image projected out toward the viewer either (with the exception, of course, of the full-aperture focused-image technique). It is bascially used for increasing the brightness of the hologram through adjustment of the reference and object beam ratios. These plates exhibit excellent brightness with single beam work. The overall “feel” of the image is very reminecent of the famous Russian single-beam work. Very low noise/scatter as well. I’m questioning whether split-beam would even be necessary, other than for H1 to H2 image-plane transfers. How Much Depth Will Pointers Record? The above digital photo shows another perspective of the same hologram, this time looking down from the top. You can see the camera going back into the plate. Once again, please take the photo into consideration, as the camera is non-focus, non-zoom and I had to get close to the hologram for the shot,
