Title (EN) POLARIZED ILLUMINATION SYSTEMS
(FR) SYSTÈMES D'ÉCLAIRAGE POLARISÉS
Abstract:
(EN) An illumination system is provided that includes a light source configured to emit a first handedness polarization of light onto a body, the first handedness polarization of light having at least one of a circular and an elliptical polarization. The body reflects a second handedness polarization of light. An optical filter is configured to at least one of absorb and reflect the second handedness polarization of light and transmit the first handedness polarization of light.
(FR) La présente invention concerne un système d'éclairage qui comprend une source de lumière configurée de sorte à émettre un premier sens de polarisation de lumière sur un corps, le premier sens de polarisation de lumière ayant une polarisation circulaire et/ou elliptique. Le corps réfléchit un second sens de polarisation de lumière. Un filtre optique est configuré de sorte à absorber et/ou à réfléchir le second sens de polarisation de lumière et à transmettre le premier sens de polarisation de lumière.
