            Abstract : 
In this paper a novel scheme of photoelastic tomography is described, to be applied to planar waveguides. It exploits the reflection of the laser probe beam at the waveguide-substrate interface to reconstruct stress distributions in waveguide cross sections. By this technique, spurious or induced local stress variations in integrated optics components can also be brought into evidence.
