RECONSTRUCTION OF OPTICAL CHARACTERISTICS OF WAVE-GUIDE LENSES BY THEUSE OF RAY-TRACING

A method that uses the data of my tracing for optical waveguide tens d iagnostics is described. This method permits a direct reconstruction o f the optical characteristics of a waveguide without the optical or th e physical thickness being measured. Conditions are determined for the mathematical problem of diagnostics by ray tracing to have a unique s olution, and a technique to obtain a numerical solution from noisy exp erimental data is described.
