Abstract

Endoscopic probes using digital speckle pattern interferometry (DSPI) have geometrical constraints which reduce the fringe quality of the images. Two experimental arrangements are presented for real-time interferometric inspection of internal parts of objects. Image processing techniques are applied to endoscopic fringes for speckle noise reduction and fringe contrast enhancement.
