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.
