Abstract:
A projection system comprising a polarization converting part for converting an incident polarization light flux into a polarization light flux having one direction, and a color separating part for color-separating the polarization light flux irradiated from the polarization converting part,the polarization converting part comprising: an FEL having a plurality of light flux dividing lenses shaped in a square and arranged in a matrix configuration, for dividing an incident light in a unit of cell; a condenser lens array for converting an incident light that is incident from the FEL, into a parallel light with respect to a specific portion; a green light filter for reflecting a part of green light of a plurality of intermediate light fluxes dividedly outputted from the FEL and passing remaining light; a polarization separating unit array for converting an incident light outputted from the condenser lens array into a linearly polarized light having a single optic axis; and a coupling lens for condensing an output light from the polarization separating unit array.
