Abstract
A scanning display includes a control unit and a scanning head linked by a tether. The control unit outputs two beams of orthogonally polarized light, each beam being modulated with a respective set of image information. The fiber is a polarization-maintaining fiber that receives the orthogonally polarized beams and carries them to the scanning head. At the scanning head, a birefringent material separates the beams spatially in response to their different polarizations. Vertical and horizontal scanners then scan the separated beams through a substantially raster pattern to produce an image.
