Abstract
An engineered video inspection lighting system includes a three-dimensional array of solid-state light emitting diodes focused to an inspection area. A single high-current, low-duration pulse is applied to selected elements of the array. Light thus generated is passed through a diffuser and to a specimen. Light reflected from the specimen is received by a lens of a video camera disposed in an interior of the three-dimensional array. Data thus obtained is used to determine acceptability of the specimen in accordance with preselected standards.
