Device to illuminate light modulator divided into section with separate illumination channel per section, for projector

摘要

Light source (1) provides unpolarized beam to first polarization divider (2) which divides light into channels (10,11) which feed light to deflection prism. End sections of both illumination channels are parallel to flat modulator area (7). Modulator area is divided into two or more sections each assigned to one light channel. INDEPENDENT CLAIM included 1) Device with second light source and four illumination channels and four modulation sections.
