A beacon modulated by a pattern is authenticated by recording an array of light intensities for each point in a field of view; digitizing the array of light intensities; modifying a first array according to the digitized light-intensities and the modulation pattern; repeating these steps for additio

A beacon modulated by a pattern is authenticated by recording an array of light intensities for each point in a field of view; digitizing the array of light intensities; modifying a first array according to the digitized light-intensities and the modulation pattern; repeating these steps for additional frames at the current viewpoint; if the beacon is found then repeating these steps for additional frames; if the beacon is found and additional frames were processed then authenticating the beacon at the point in the current viewpoint corresponding to the value in the first array that exceeds a first threshold by the widest margin; if the beacon was not found, moving to a new point in the field of view and repeating the steps above; if the beacon is again not found, adjusting the modulation bit pattern x bits, and reprocessing the viewpoints in the field of view using the steps above.

The luminaire can include at least one remote reflector at least partially surrounding the refractor assembly for further distributing light being received from the refractor assembly. The light source may be attached to a post intended to be set into the ground, and said refractor assembly including a radial lens and the radial lens can include a collimating ring section and a flange disk section.
