Abstract

A system for measuring the profile or the refractive index of a transparent object by fringe projection techniques is provided and has an image generating device, an image capture device, and an image processor. The image generating device produces a reference image with a long depth of focus. This reference image is emitted into an inspected transparent object, and is distorted by the refractive index and the profile of the transparent object. The image capture device receives the distorted image. The image processor analyzes the difference between the distorted image and the reference image, so as to identify the profile or the refractive index of the inspected transparent object.
