摘要： This disclosure provides systems, methods and apparatus for an imaging system that includes a light guide having light-turning features that are configured to receive ambient light incident on the light guide, including light scattered from a scene to be imaged, and to direct the received ambient light towards an image sensor. The light-turning features may have angle-discriminating properties so that some light-turning features capture light incident upon the light guide at certain angles of incidence, but not others. Light scattered from multiple parts of a scene to be imaged may then be directed to correlated locations on an image sensor, which provides electronic data representing an image.

摘要： One embodiment of the present invention is a visual field tester that includes: (a) a high intensity light source; (b) an optical fiber; (c) scanning optics, wherein light output from the light source is directed by the optical fiber to impinge upon the scanning optics, and the scanning optics directs the light to form a stimulus at various field positions; and (d) a video display system to output one or more light patterns. Another embodiment of the present invention is a visual field tester that includes: (a) a video display system to output one or more types of light patterns; (b) a background illumination display system; and (c) viewing optics to magnify the field of view of the video display system and the background illumination display system. Still another embodiment of the present invention is a visual field tester that includes: (a) a video display system to output one or more types of light patterns; and (b) a background illumination display system that outputs variable intensity light, wherein the video display system includes: (i) a variable intensity, high brightness light source and (ii) a light modulator display disposed to transmit light output from the source.
