holography
Figure 1: Gabor's original method for creating holograms.
A real image produced by a hologram can be captured using ordinary photographic means by positioning a camera or microscope at the specific location in space where the real image is formed.1
Because the hologram stores both amplitude and phase information, the reconstructed real image possesses three-dimensional characteristics, allowing the camera to be focused on selected depths of the object with precision. It is important to note that this real image appears pseudoscopic, or with reversed curvature. To correct this reversal, one can create a double hologram by using the initial hologram as an object to produce a second one, which restores the image to its normal orientation.1
