It is generally believed that the holographic image of an object is perceived by a person as though it is the real object. In the course of our experimental work, we have had reason to question this belief. We reviewed the literature to determine if data obtained from human observers exists to support the belief and found that it did not. Thus, we initiated experimentation to gather it. We used the psychophysical method of adjustments to study distance perception of actual objects and holographic images of those objects. The data indicates that, for our test conditions, the belief is not supported.
