Abstract:
1. A method comprising: integrating a light beam from a light source; splitting the integrated light beam at a first location into at least a first cone of light and a second cone of light, wherein the first cone of light has a first intensity distribution and the second cone of light has a second intensity distribution that is complimentary to the first intensity distribution; directing the first cone of light onto a first spatial light modulator and directing the second cone of light onto a second spatial light modulator; modulating the first cone of light by the first spatial light modulator to create a third cone of light and modulating the second cone of light by the second spatial light modulator to create a fourth cone of light; combining the third cone of light and the fourth cone of light at a second location into combined light, wherein the second location is separate from the first location; and projecting the combined light.
