Abstract
A process and system capture infrared light that is reflected or emitted from a device to precisely locate the device. The process and system project visible light from a light source toward the device such that the light is precisely targeted at the device. Preferably the visible light passes through an atmosphere containing particulate matter rendering the visible light as a beam that appears to emanate from the device rather than from the light source.
