ABSTRACT:
The present invention relates to improved optical devices and reflection control techniques. In one aspect, the invention provides an optical device comprising an array of substantially tubular elements and one or more reflective surfaces, wherein at least one of the reflective surfaces positioned behind the tubular elements is tilted with respect to the optical path of the device. This orientation of the reflective surface results in incident light from a source in the field of view of the device being reflected from the tilted surface and captured by the array of elements, rather than the reflected light being projected outward from the device where it can be perceived by a viewer, particularly a viewer in the field of view.
