Abstract:
A reduced product height/thickness projector includes an illuminator, an electro-optic modulator, a projection system, a collector lens, and associated housing. The illuminator including a light source that emits an illumination light flux, a first lens array having a plurality of first lenslets that divide the illumination light flux from the light source into a plurality of sub-light fluxes, a second lens array having a plurality of second lenslets corresponding to the plurality of first lenslets, and a superimposing lens that superimposes the sub-light fluxes from the second lens array on an illuminated area. The central axis of the image formation area of the electro-optic modulator and the lens optical axis of the superimposing lens is shifted from the light source optical axis of the light source. The lens optical axis of the collector lens is shifted opposite from the central axis of the image formation area of the electro-optic modulator.
