Abstract
A tunable liquid-crystal etalon filter comprising two dielectric stack mirrors (18, 20) defining an optical cavity into which is filled a liquid crystal (26). Electrodes (14, 16) disposed on the outsides of the mirrors apply an electric field to the liquid crystal, changing its refractive index and thereby changing,its optical length.
Thereby, the optical pass band of the filter can be electrically changed in a low-powered, compact, rugged, and economical structure.
Thereby, the optical pass band of the filter can be electrically changed in a low-powered, compact, rugged, and economical structure.
