DEFINITION

Classification: 250/208.6

With specific relative positional geometry of photosensitive elements (e.g., an annular photosensitive element surrounding a coaxially mounted photosensitive element):

(under subclass 208.2) Subject matter in which the plural photosensitive elements are arranged in a predetermined, specific geometric orientation relative to each other to provide a desired result, e.g., detecting specularly reflected light as well as diffusely reflected light from an object viewed by the photosensitive elements.
