ABSTRACT:
A light separating element designed to have parallel first and second external surfaces, a first polarizing film disposed on the first external surface and arranged to reflect a first portion of a first component in a first direction and transmit a second portion of the first component and all of a second component in a second direction. Further, a second polarizing film can be disposed on a second external surface which reflects a first portion of the second component in a third direction and transmits a second portion of the first and second components in a fourth direction. Further, the first portion of the second component is reflected by the second polarizing film to strike the first polarizing film. The first polarizing film transmitting a first portion of the second component in a fifth direction or a reflecting surface disposed on the second external surface and arranged to reflect a second portion of a first component and all of a second component in a third direction toward the polarizing film. The first portion of the second component is transmitted by the polarizing film in a fourth direction and a second portion of the second component and the second portion of the first component are reflected in a fifth direction toward the reflective surface. The second portions of the first and second components traveling in the fifth direction are reflected by the reflective surface in a sixth direction toward the polarizing film and the second portions of the first and second components traveling in the sixth direction are transmitted by the polarizing film in a seventh direction.
