Compact biocular viewing system for an electronic display |
| abstract |
Low-cost plastic optics allow biocular viewing of video images with a single electro-optic display device. Folded and unfolded dual off-axis configurations use collimated illumination and intermediate imaging optics to fill both eyepieces from a single display device without requiring beamsplitters. Multiple illumination schemes provide either monochrome or color, either two-dimensional or time-sequential true stereographic presentation. Light from multicolor sources is superimposed using dichroic mirrors. A display field lens proximate to the display surface collimates the illumination beam. A shaping lens provides substantially uniform illumination of the display surface. An aperture stop improves image quality by blending sub-pixel higher order spatial harmonics from the display device. Offsetting color over- and under-correction of individual optical elements provides overall chromatic correction with minimal optical complexity. Lightweight optical elements and injection-molded unitary plastic structures containing multiple optical elements reduce cost and complexity. A wireless video interface eliminates excess cabling. |
