Abstract
A wavelength conversion device comprising a plurality of regions. Each region for absorbing radiant energy and emitting light having a characteristic dependent upon which region of the device emits the light.
Claims1
A method of converting radiant energy comprising:
- directing a first radiant energy beam at a moving surface;
- absorbing a portion of the first radiant energy beam;
- emitting a second radiant energy beam, the second radiant energy beam having a characteristic dependent upon the composition of the moving surface, wherein different regions of the moving surface emit radiant energy having different characteristics;
- and
- moving the moving surface relative to the first radiant energy band such that the first radiant energy band impinges on different portions of the moving surface, wherein the regions are arranged in annular bands on the moving surface.
