Implementation of a Controller for a Space-Grade, Piezo-Actuated Fabry-Perot Interferometer

Implementation of a Controller for a Space-Grade, Piezo-Actuated Fabry-Perot Interferometer

A tunable Fabry-Perot interferometer (FPI) can be used as an optical band-pass filter. This type of filter is used in spectrometers and spectral imagers. The transmitted wavelength depends on the optical cavity adjusted by an electronic controller. This cavity, or the gap between the FPI mirrors, is...
