Abstract

This research was motivated by the desire to improve the capability of Michelson Doppler interferometers in order to cope with situations of rapid temporal variablity encountered in upper atmospheric physics.¹ A Michelson phase quadrature interferometer has been constructed using Phase Quadrature Mirrors (PQMs), based on optical multilayer coatings, in order to eliminate scanning mechanisms and achieve a fast time resolution over a very broad wavelength region. Other advantages include greater simplicity, improved ruggedness and lower cost.
