Abstract
The resonance characteristics of a twisted-nematic liquid crystal Fabr y-Perot wavelength filter (TN-FP) is analysed and it is shown that it obeys some simple laws hitherto unknown. A method to calculate the tra nsmittance and eigenstate of polarizations of the filter is first demo nstrated. Next, approximate expressions of resonance wavelengths at so me of the voltage regions are derived and connection formulae for two series of modes are presented. Finally, a transition of the eigen pola rization in the FP etalon is investigated, and an interpretation of a paradoxical property concerning the longitudinal mode number of the fi lter is given.
