Paper Abstract

Measuring surface topography of translucent objects with phase shifting fringe projection method is a challenge because of the reduced fringe contrast due to the scattering inside the object. The internal structure also has an impact to the measurement. We present a new phase shifting fringe project imaging method to measure three-dimensional surface shapes of translucent objects. This method employs polarized short wavelength to increase the fringe contrast by reducing the internal scattered light from reaching the camera.
