Abstract: A multi-spectral stereoscopic display system is disclosed. A left-eye image may be presented and viewed via a first set of spectral bands. A right-eye image may be presented and viewed via a second set of spectral bands. The two sets of spectral bands may have low or no overlap with each other. The color balances of the left-eye image and the right-eye image may be almost matching or identical. The left-eye image and the right-eye image may each be a full-color image with neutral color balance, even without modifying the color balance of original image content. Thin-film optical interference filters may provide pass-bands corresponding to these sets of spectral bands. The filter design may lead to an inexpensive viewing apparatus that can be mass-produced using inexpensive glass or polymer substrates. This system does not rely on polarization techniques and may be used with a white or metallic display screen.

Abstract: A multi-spectral stereoscopic display system with additive and subtractive techniques is disclosed. Stereographic images may be presented and viewed via two sets of spectral bands that may have low or no overlap with each other. The color balances of a left-eye image and a right-eye image may be almost matching or identical. The left-eye image and the right-eye image may each be a full-color image with neutral color balance, even without modifying the color balance of original image content. Additive and subtractive techniques may provide spectral content within these sets of spectral bands. Subtractive techniques may include spectral filters. Additive techniques may include multi-spectral illuminants. An arrangement of a set of spectral bands may correspond to natural resonant characteristics. The spectral bands may be determined independently of conventional RGB designation of spectral bands.
