Fringe Analysis And Interpretation

Misinterpretation of the fringe order and errors in determining its value is one of the greatest, if not greatest, shortcomings in photomechanics. Three methods are herein proposed which either improve upon or automate existing procedures. The methods, in the order presented are: 1) Carrier Fringe Methods, 2) Coherent Compensation, and 3) Color/Load Coding.
