Suppression of Disturbing Light Reflexes in Holography, Applied to Practical Recording Problems in Medicine and Technology

Abstract

In many applications of holographic interferometry it is unavoidable that reflecting media are positioned between object and hologram (see Figure 1). These may be lenses (e.g. in an otoscope or a microscope) or semireflecting mirrors, as often used for a direct observation parallel to the illuminating beam. Sometimes during investigation an object has to be placed in a specific test chamber (e.g. a pressure chamber or a liquid cell containing physiological solutions).
