Abstract:
1. A polarization diversity system comprising: a first polarizing beam splitter for receiving an input beam of light and splitting the input beam of light into a first beam of light polarized in first direction and a second beam of light polarized in a second direction; a first optical path comprising: a first deflector made from polymer-dispersed liquid crystal elements; a half-wave plate; a second deflector made from polymer-dispersed liquid crystal elements; and a mirror, wherein the first optical path receives the first beam of light polarized in a first direction from the first polarizing beam splitter and outputs the first beam of light polarized in a second direction; a second optical path comprising: a mirror; a third deflector made from polymer-dispersed liquid crystal elements; a half-wave plate; and a fourth deflector made from polymer-dispersed liquid crystal elements, wherein the second optical path receives the second beam of light polarized in a second direction from the first polarizing beam splitter and outputs the second beam of light polarized in a first direction; and a second polarizing beam splitter for receiving the outputted first beam of light polarized in a second direction from the first optical path and the outputted second beam of light polarized in a first direction from the second optical path.
