Paper Abstract

One of the more popular optical methods for gaging part dimensions has been the use of structured light. As the measurement requirements for these gages increases, the need for more accurate system design becomes evident. This paper presents two approaches to "structured light" applicable to high precision gaging, beyond that of any traditional optical cross section measuring transducer. The design goals were an accuracy of + one part in three thousand over the transducers' field of view, for fields of view ranging about a centimeter to 30 centimeters with comparable depths-of-field, a standoff distance of at least 15 centimeters, with the coordinate data generated in one second or less. We have considered multiple systems in this effort and have considered for what applications each would be most appropriate.
