Abstract
The interior surface of a pipe is optically inspected by a scanner including an array of photodiodes, a light source, and mirrors for directing light reflected from the interior surface to the photodiode array. The charges developed by the photodiodes are converted to digital data which is subtracted from a reference signal for an unblemished interior surface area. The difference is recorded in a memory and displayed on a monitor for defect analysis.
