IPC: G02B3/00
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To prevent trouble that the contrast of an aerial picture is lowered and observation gets hard and to realize the display of a three-dimensional picture having complete contrast by shielding a gap between respective lens elements from light by a light shielding member. SOLUTION: An arraying member 11 for arranging plural lenses 1 is constituted to be opaque with light shielding property. When an original picture 20 is exactly placed at the original position of a dry plate and illuminated from the back side of the original picture 20 by a light source 30 so as to be observed through a lens array 10, a light beam is reproduced by tracing a path reverse to that at the time of photographing. Therefore, the aerial picture of a subject is reproduced as the three-dimensional picture at the same position as the subject at the time of photographing. Thus, the aerial picture corresponding to the subject in the case of producing the original picture 20 is formed as the three- dimensional picture on a viewing point side (observer side).  By shielding the gap formed between the respective lenses 1 from the light by the light shielding member (arraying member 11), the light from the light source. 30 is prevented from being directly leaked to the viewing point side.
