ABSTRACT:
Low-cost complex plastic optics allow biocular viewing of video images generated by a single electro-optic display device, such as in a head-mounted display (HMD) for commercial or medical viewing applications. A dual off-axis configuration uses nearly collimated illumination optics and intermediate imaging optics to fill both eyepieces from a single display device without the need for a beamsplitter. Multiple illumination schemes are provided for either monochrome or color, and in either two-dimensional or time-sequential true stereographic presentation. Light from multicolor sources is superimposed, mixed, and homogenized by mixing light cones with diffractive collectors. Offsetting color overcorrection and undercorrection of individual optical elements achieves overall chromatic correction with minimal optical element complexity. A wireless video signal interface eliminates excess cabling. Additional features include lightweight achromatic eyepiece construction and interchangeable lenslets for peripheral vision correction. Multiple optical elements are injection-molded as a unitary plastic structure, thereby reducing cost and complexity.
