Abstract
An illuminator including a differential optical radiator and a laser fiber disposed within the differential optical radiator. The differential optical radiator includes a first region that has a first level of reflectivity and a first level of transmissivity and a second region that has a second, higher level of reflectivity and a second, lower level of transmissivity. The first and second regions are positioned such and their reflectivities and transmissivities are chosen such that the radiator produces a substantially uniform pattern of illumination from the first and second regions. In another embodiment, the illuminator includes an expandable radiator and a laser fiber disposed within the expandable radiator. The reflectivity of the expandable radiator is such that the illumination at the outer surface of the expandable radiator is substantially uniform.
