Paper Abstract

Small angle moire has been shown to be very useful in contouring objects with steep slopes and protrusions. We have considered a system which uses only one lens which serves as both the projection and viewing lens, that minimizes some of the problems associated with producing a small angle moire. The compactness of the design of a single lens system offers potentially higher stability, at the loss of standoff and field coverage from conventional designs. This paper explores the pros and cons of the single lens moire contour method, and discusses new problems of alignment and noise unique to this approach. Finally, the performance results of a test unit will be presented.
