ADDING CONTENT TO A PROGRAM

摘要

Mechanisms for adding content to a projected light stream are disclosed. A polarization rotation panel receives content and generates a polarization rotation pattern based on the content. The polarization rotation panel receives at least a first portion of a first projected light stream that has a first polarization orientation. The first polarization orientation of a sub-portion of the at least the first portion of the first projected light stream is rotated an offset amount to a first offset polarization orientation in accordance with the polarization rotation pattern, and the at least the first portion of the first projected light stream and the sub-portion are issued in a downstream direction.
