Paper Abstract
A nematic liquid crystal Fabry-Perot interferometer (NLC-FPI) based on nematic material in a parallel configuration
is described, for applications in astronomy. This device allows spectral chopping for an efficient removal of background
radiation, when the source is embedded in a strong background such as the solar corona or IR sources. The
primary design is intended for two-dimensional spectroscopic imaging. This method is also very useful for precision
spectropolarimetry. The NLC-FPI is a tunable, double-channel filtec we present some theoretical and experimental
results obtained on a first generation pmtotype.
