Embodiment Construction

[0022]Examples disclosed herein is a stereoscopic imaging system that uses illumination light with narrowband spectrum to generate stereoscopic images such that the generated images can be visualized using passive glasses, in particular, passive glasses integrated with interference filter technology (Infitech). By narrowband, it is meant that the full-with at half maximum (FWHM) of the light spectrum is 100 nm or less, more preferably 50 nm or less, and 30 nm or less.

[0023]Turning to the drawings, FIG. 1 is a diagram schematically illustrates an exemplary stereoscopic display system within the scope of the invention. Stereoscopic imaging system 100 in this particular example comprises illumination system 102, image engine 110, synchronization unit 112, color processor, right lens filter 114, and left lens filter 116.

[0024]Illumination system 102 is capable of emitting narrowband illumination light beams with different waveband spectra. Subject to the constraint that the maximum numb...

Abstract

A stereoscopic display system employs narrowband illumination light beams and passive glasses with built-in interference filters. The system is also compatible with multiple viewing functions.

Description

TECHNICAL FIELD[0001]The technical field of the examples to be disclosed in the following sections relates to the art of display systems, and more particularly, to the field of stereoscopic imaging systems using solid-state illumination and passive glasses.BACKGROUND OF THE INVENTION[0002]Traditional stereoscopic imaging systems for visualization of virtual objects use active shutter glasses and passive polarization glasses. Active shutter glasses incorporate left and right shutters that are synchronized to the sets of images for left and right eyes (left and right images). This approach, however, adds cost and introduces artificial effects, such as flickers as each side of the glasses turns on and off.[0003]Passive glasses work in systems employing polarized light and incorporate left and right polarizers that are typically offset by 90° degrees. Due to the polarization, brightness and optical efficiency can be significantly reduced.[0004]Therefore, there exists a need for cost eff...
