摘要： A Fabry-Perot interferometer contains a twisted nematic liquid crystal (3) and means for applying an electric field across the crystal. The twist is suitably 90°. When a sufficient electric field is applied across the liquid crystal (3) the interferometer becomes insensitive to the polarisation of incident light.
