Abstract

See full text

A device for producing an output light emission having a light source for emitting light and a first polarizing beam splitter element positioned so at least one portion of the emitted light is incident thereupon, wherein a first reflected light beam of a first polarization state and a second transmitted light beam of a second polarization state are produced. The device also includes a first liquid crystal element having at least two states which are actuated using a control unit. The first liquid crystal element at least partially reflects the first light beam, wherein the polarization state of the first light beam is altered based on the state of the first liquid crystal element. The first polarizing beam splitter element is positioned so the first light beam is incident thereupon after reflection at the first liquid crystal element.
