Abstract
An optical probe apparatus and method for determining a position of an image sensor within a digital camera relative to a reference surface. The apparatus includes an optical probe assembly removably mountable to the digital camera. A non-coherent light interferometer in communication with the optical probe assembly is utilized to determine a depth from a reference surface to the image sensor and optical probe assembly.
