A fiberoptic electronic speckle pattern interferometer illuminated with a diode-laser source has led to a novel system that allows shape measurement. The technique utilizes the modulation of the diode-laser wavelength to produce height contours of the object under study. This technology has been combined with a phase-stepping algorithm to produce a contour map of the object surface and, therefore, a representation of its shape. Results from a profiling study of a gas-turbine compressor blade using contours from 0.9 to 8 mm are presented.
