Abstract
A new optical visualization technique is discussed which provides a simple yet dramatic means to view local shape variations in quasi flat objects. Sensitivity of this technique is such that depressions or protrusions on the order of 0.025 mm are readily visible. Examples of several applications of this technique in industry are shown.
