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.
