The housing has an aperture through which a surface recessed into the housing is aligned with the imaging device by the fixture. A planar electroluminescent illuminator is held in the fixture within a pocket of the fixture in which the housing is received. The illuminator uniformly emits light in response to electrical power applied thereto and the illuminator has an aperture formed therein held in alignment by the fixture with the aperture in the housing such that the light emitted by the illuminator is directed towards the recessed surface. An imaging device generates an image of the recessed surface through the aperture in the housing and the aperture in the illuminator."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Uniform lighting of surfaces for visual inspection","description":"A fixture retains a housing in a fixed position relative to an imaging device.
