High efficiency electromagnetic beam projector and systems and method for implementation thereof
First Claim
1. A method of producing a substantially collimated beam of electromagnetic energy having substantially the same selected predetermined orientation of a chosen component of electromagnetic wave field vectors and a substantially uniform flux intensity substantially across the beam of electromagnetic energy, comprising:
- [a] providing a substantially collimated beam of electromagnetic energy having a predetermined range of wavelengths;
[b] resolving from the substantially collimated beam of electromagnetic energy a substantially collimated first resolved beam of electromagnetic energy having substantially a first selected predetermined orientation of a chosen component of the electromagnetic wave field vectors and a substantially collimated second resolved beam of electromagnetic energy having substantially a second selected predetermined orientation of a chosen component of the electromagnetic wave field vectors, whereby the first and second selected predetermined orientation of the chosen component of the electromagnetic wave field vectors are different from one another;
[c] intercepting the second resolved beam at a first location along the beam optical path and shifting the field vector orientation by a first non-zero increment to produce a first phase shifted resolved beam;
[d] intercepting the first phase shifted resolved beam at a second location along the beam optical path spaced apart from the first location and shifting the field vector orientation by a second non-zero increment to produce a second phase shifted resolved beam having a field vector matching the field vector of the first resolved beam; and
[e] redirecting and combining the first resolved beam and the second phase shifted resolved beam into a single composite beam to form a substantially collimated single beam of electromagnetic energy having substantially the same selected predetermined orientation of a chosen component of electromagnetic wave field vectors substantially across the substantially collimated single beam of electromagnetic energy and a substantially uniform flux intensity substantially across the substantially collimated single beam of electromagnetic energy.

Abstract
This invention relates to electromagnetic wave beam paths, formation of the beam, illumination of programmable electromagnetic wave field vector orientation rotating devices (“PEMFVORD”) with an electromagnetic beam, and the technique of projection of the modulated beam. This invention also relates to a unique light path and method of forming the light into a rectangular beam to be used for optical projection systems and, more particularly, in a color and/or black and white liquid crystal device (LCD) projectors that produce high resolution, high brightness and/or three-dimensional images. This invention further relates to a device capable of receiving and displaying two-dimensional and three-dimensional images.
