Abstract
This invention discloses an apparatus for optically inspecting an object having upper and lower faces for indicating the condition of the object, including a lighting system periodically reflecting a beam of light from one face of the object to produce a series of short-duration time-spaced reflected beams, and periodically transmitting a beam of light through both faces of the object to produce a series of short-duration time-spaced transmitted beams time-interlaced with the reflected beams, a sensor sensing the short-duration time-spaced reflected beams and transmitted beams, and generating electrical outputs corresponding thereto, and a processor receiving the electrical outputs and processing them to provide an indication of the condition of the object. A method of optically inspecting an object having upper and lower faces for indicating the condition of the object is also described.
