Abstract :
Summary form only given. We describe here an ESPI technique based on a carrier generation on the object by wavelength shifting of the emission of a laser diode. This technique generates reference fringes on the object. Tilting of the fringes can be used for high sensitivity measurement of the angular rotation of the object.
