Abstract:
An image projecting apparatus comprising:supplying means for supplying polarized light;forming means for forming an image light with said polarized light, said forming means including at least one light modulating element for modulating the polarizing light and at least one polarizing plate for receiving said modulated polarized light, said polarizing plate being provided separately from said light modulating element; andprojecting means for projecting said image light, said projecting means having a pupil;wherein said supplying means comprises:a lens array for separating light from a light source into a plurality of light beams;a polarizing beam splitter array for splitting each of said plurality of light beams into P-polarized light and S-polarized light;a .lambda./2 film array for making polarization directions of said P-polarized lights and said S-polarized lights consistent; anda condenser system for condensing said P-polarized lights and said S-polarized lights whose polarization directions have been mutually consistent to said forming means and for directing them to the pupil of said projecting means.
