Abstract
This paper describes a noncontact visual profile sensing method and an implementation for the inspection of metal turbine parts for visual surface defects. The inspection system consists of two sensors, each with its associated hardware preprocessor, and a manipulation system. Four general purpose computers control the entire system and perform high level part quality decisions. One cpu serves as the system executive, two serve as high-level image pro-cessors in concert with the two sensors and preprocessors, and one cpu serves as a controller for the fifteen servo axes which comprise the manipulator system. This paper will describe the sensor and the preprocessor hardware. It provides additional information to a previous paper describing only the profile sensing scheme. For ease of reading, some previous material is repeated from the reference.1
