COMPACT STEREOSCOPIC PICTURE TAKING SYSTEM

摘要

A stereoscopic picture taking systems includes a first camera having a first optical objective, and a second camera having a second optical objective, where the optical characteristics of the two objectives are substantially identical. The stereoscopic system also includes a plane semi-reflecting plate in front of the first objective and inclined by a predetermined angle on the optical axis of the first objective. The stereoscopic picture taking system also includes an optical element having a plane reflecting surface disposed at the level of the second objective and inclined by the same predetermined angle on the optical axis of the second objective such way that the main part of the optical axis of the second objective is substantially parallel to the optical axis of the first objective. This optical element can be a plane mirror or a return prism. The first objective has a plate of identical optical thickness.

1. A stereoscopic picture taking system, comprising:
a first camera comprising a first optical objective; a second camera comprising a second optical objective, wherein optical characteristics of the first optical objective are substantially identical to optical characteristics of the second optical objective; and a plane semi-reflecting plate disposed in front of the first optical objective and inclined by a predetermined angle on an optical axis of said first optical objective, wherein the first optical objective comprises a first optical sub-assembly disposed in front of said first optical objective, the first optical sub-assembly comprising a thick glass plate, wherein the second objective comprises a second optical sub-assembly in front of said second optical objective, the second optical sub-assembly comprising a return prism comprising a plane reflecting surface, and wherein an optical thickness of said return prism being identical to an optical thickness of the thick glass plate, said plane reflecting surface being inclined substantially by the predetermined angle on an optical axis of said second optical objective such that a main part of the optical axis of the second optical objective is substantially parallel to the optical axis of the first optical objective.
