Spectral stereoscopic projection system

A stereoscopic digital projection system that projects stereoscopic images including first-eye images and second-eye images onto a display surface, comprising:

• narrow-band, solid-state, red, green and blue first-eye light emitters having corresponding red, green and blue first-eye spectral bands with respective red, green and blue first-eye central wavelengths, λR1, λG1 and λB1;
• narrow-band, solid-state, red, green and blue second-eye light emitters having corresponding red, green and blue second-eye spectral bands with respective red, green and blue second-eye central wavelengths, λR2, λG2 and λB2, the first-eye spectral bands being substantially non-overlapping with the second-eye spectral bands, and the central wavelengths being arranged such that λB1<λB2<λG2<λG1<λR1<λR2;
• an image forming system including at least one spatial light modulator for forming a first-eye modulated image by modulating light from the red, green and blue first-eye light emitters responsive to image data for a first-eye image and for forming a second-eye modulated image by modulating light from the red, green and blue second-eye light emitters responsive to image data for a second-eye image;
• and
• projection optics for delivering the first-eye modulated image and the second-eye modulated image to a display surface.
