Abstract: front page image
(EN)The invention is an optical unit that includes a polarizing beamsplitter (PBS). The PBS includes a reflective polarizer that transmits a portion of a light beam that has a first polarization and reflects a portion of the light beam that has a second polarization. A light absorbing device is operatively disposed relative to the PBS. The light absorbing device receives the light either transmitted or reflected by the PBS. The light absorbing device includes a light capture portion having a structured surface.
(FR)L'invention traite d'une unité optique qui inclut un séparateur de faisceau de polarisation (PBS). Le PBS inclut un polariseur réflectif qui transmet une partie d'un faisceau lumineux qui a une première polarisation et réfléchit une partie du faisceau lumineux qui a une seconde polarisation. Un dispositif d'absorption de lumière est disposé de manière opérationnelle par rapport au PBS. Le dispositif d'absorption de lumière reçoit la lumière soit transmise ou réfléchie par le PBS. Le dispositif d'absorption de lumière inclut une partie de capture de lumière ayant une surface structurée.
