摘要:
Systems and methods are described employing a first lens array and a second lens array that are separated by one focal length that receives a plurality of colors signals from an X-prism and transmits to a condenser for overlapping lenslet images onto a display panel, such as a LCOS or LCD display panel. The first lens array includes a plurality of lenslets where each lenslet in the first lens array corresponds with each lenslet in a plurality of lenslets in the second lens array. The lenslets can be either refractive, defractive, or a combination of refractive and defractive.
