Abstract

The invention provides a light field information coupler. The coupler comprises a light splitting element and a light trap, wherein the light splitting element comprises a light splitting surface, a light beam incident end, a light beam emergent end, a light beam coding end and a light trap end, a light beam to be coded enters the light splitting element from the light beam incident end and is divided into two paths through the light splitting surface, one path is turned and then emitted to the light trap from the light trap end for extinction, and the other path is emitted from the light beamcoding end, is converted into a coded light beam after light field coding, is reflected back to the light splitting element, and is emitted from the light beam emergent end after being turned back bythe light splitting surface. By arranging the light trap, the light energy which does not participate in normal coding output is absorbed, and the influence of the energy on the output coding light beam in a stray light form is eliminated. In addition, an extinction reflector plate, an antireflection film and other structures are added to an optical splitter, and the small inclination angle design of the optical surface is carried out, so that the multiple reflected light of the optical surface deviates from the coding light path, and the influence of the multiple reflected light on the coding light beam in a stray light form is significantly reduced.
