Abstract:
1. A method of lighting an object comprising: a) directing a light beam along a light path and past a first pixelated spatial light modulator (SLM) configured to accept the light beam, the first pixelated SLM configured to shutter the light and pass substantially only desired light impinging on the first pixelated SLM as a partially shuttered light beam, b) directing the partially shuttered light beam past a second pixelated SLM configured to accept the partially shuttered light beam from the first pixelated SLM and to pass substantially only desired light impinging on the second pixelated SLM as a post-shutter light beam, wherein the first and second pixelated SLMs are operably connected to at least one controller containing computer-implemented programming that controls an on/off pattern of pixels in the first and second pixelated SLMs to display substantially the same shutter configuration and thus to simultaneously reject a substantially same pattern of non-desired light from the light beam or the partially shuttered light beam, respectively, and to pass desired light as the post-shutter light beam consisting substantially only of a desired selected light output.
