Scanning illumination-acquisition system for noncontact optical tomography

Abstract

A new method for the detection of light traversing a diffuser/nondiffuser interface and its simultaneous determination for optical tomography is proposed, and the preliminary results are shown. The method is based on the use of a point detector and two uncoupled scanning systems-one for illumination and the other for registration-together with active modification of the optics guided by the surface topography to generate virtual detectors on the interface.
