| Popis: | This paper presents a solution of the straight-through transformative problem for an anisotropic optical channel, using as an example a crossed interference–polarization Wood–Solc filter in the visible region. Based on experiments, the effective thickness is computed for a system composed of two quasi-plane-parallel lithium niobate phase plates that constitute the filter. A new accelerated method has been developed for analyzing interference patterns at the filter output that makes it possible to estimate the thickness difference between a reference plate and a test plate, beginning with 4 µm at a temperature of 20°C without using additional measurement devices. |
