ABSTRACT:
An optical system and a projection system incorporating same are disclosed. The optical system includes a light source that is capable of emitting light. The emitted light includes one or more substantially collimated discrete light beams. The optical system further includes a lenslet array for receiving and transmitting the emitted light. Each discrete light beam in the emitted light has an intensity full width at half maximum (FWHM) at the lenslet array that covers at least a portion of a plurality of lenslets in the lenslet array. The optical system further includes an optical element for receiving the transmitted light from an input face of the optical element. The optical element homogenizes the received light and transmits the homogenized light from an output face of the optical element.
