Projection of 3D Images
Basically, projection of 3D images involves:
- Use of a dual-lens projector, or two single-lensed projectors.
- Polarized filters over each projection lens, aligned at right angles.
- Use an aluminum (silver) or lenticular (with vertical lens ridges)
projection screen. Normal beaded or white
projection screens will de-polarize the light projected, destroying the
stereo effect. The silver or lenticular screens will preserve the
polarization of the projected light, essential for maintaining a left
and right image.
- Polarized glasses are worn which match the alignment of the projector
lens polarizing filters. In most projectors and glasses, the orientations
of the polarization is in a "V" shape.
