A polarization luminaire is disclosed having a light source that emits
light having random polarization directions, a first lens plate and a
second lens plate. The first lens plate has a plurality of condenser
lenses, the condenser lenses being decentered lenses. The second lens
plate is a composite layered element having a condenser lens array, a
polarization beam splitting prism array, and a half-wave plate placed on
an exit side of the polarization beam splitting prism array. The
polarization beam splitting prism array splits each light emitted from
both the plurality of condenser lenses and the condenser lens array into
a p-polarized light and an s-polarized light. The polarization beam
splitting prism array includes a plurality of polarizing beam splitters
and a plurality of reflecting mirrors alternately arranged.
