Real-time holographic interferometry can be used to determine the displacement and deformation of an object which has been stressed. phase-measuring techniques can and have been added to provide quantitative information about the deformation of the object in one particular direction. in order to… More

Optical instruments for performing linewidth measurement or for finding the geometry of small features are limited by the resolution associated with the wavelength of light. basic optical theory states that features smaller than one-half of the illumination wavelength are unresolvable. however,… More

WYKO proposes to demonstrate the feasibility of an optical contouring system that will quickly measure the shape of both the resting and loaded foot to allow automated manufacture of therapeutic footwear directly from the data provided in an open architecture format. This bypassess the steps of… More
