Abstract:
Embodiments are disclosed of a lighting apparatus including a fixture adapted to accommodate a camera having imaging optics that define an optical axis, wherein the fixture includes an open end through which the imaging optics can capture an image. One or more side-emitting illumination light sources are positioned adjacent to the open end, the plurality of side-emitting light sources positioned to direct light toward a plane intersected by the optical axis. Other embodiments are disclosed and claimed.
Abstract:
An illumination system can provide and/or utilize a system comprising a first sheet (1400) formed of a light-diffusing material, said first sheet defining a pair of opposing faces (1410,1420) and two pairs of opposing edges (1430,1440), said first sheet adapted to provide a substantially uniform illumination from at least one (1410) of said faces when light is transmitted into any of said edges; a first reflective layer (1500) adapted to reflect light toward a second face of said pair of faces,- a second sheet (1700) formed of a light diffusing material; and a first light source (1210) adapted to transmit light into a first edge of said edges.
