|Abstract: ||The incorporation of laser diodes and monomode fibre optics into an Electronic
Speckle Pattern Interferometer (ESPI) has led to the development of a novel
holographic surface contouring system. Height contours are obtained by switching
between two laser wavelengths. Contour intervals from 0.5-5 mm have been
generated by modulating the injection current of a single laser diode source and
are demonstrated on an automotive disc brake hub.|
