Abstract:
1. An integrator, comprising: a recycling unit having longitudinal sides and an end section, wherein the end section and at least a portion of the longitudinal sides are adapted to reflect incident input light; an incident unit positioned on an input end of the recycling unit, wherein the incident unit comprises: a first polarizing plate positioned in the recycling unit so as to transmit a first polarization state and reflect a second polarization state towards a longitudinal side of the recycling unit; and a second polarizing plate positioned on a longitudinal side of the recycling unit and positioned to receive the second polarization state reflected by the first polarizing plate, wherein the second polarization plate is adapted to reflect the first polarization state and transmit the second polarization state out of the recycling unit.
