Abstract
We have proposed a simple correlation algorithm to extract weak distorted f ringes buried in both background noise and random noise. The relationship a mong threshold value, signal to noise ratio and least frame number was disc ussed. The method, is efficiency to measure the shape of an object with low diffuse reflectivity. We have successfully applied the method to measure t he shape of a dragonfly wing. (C) 2001 Elsevier Science Ltd. All rights res erved.
