DURING a course of experiments with interferometers it was found that a very simple and inexpensive Fabry and Perot instrument could be constructed of plate glass which gives results almost as good as ...

Application of the Fabry-Perot interferometer instrument to study upper atmosphere dynamics has been one of the primary tools of ground-based optical aeronomy research ever since the beginning of the ...

Optical Surfaces Ltd. reports on the development of a new polishing technique that has been shown to reproducibly improve the spectral filtering capability (finesse) of Fabry Perot etalons. For over ...

Trace gas sensors are used in different fields. Light-induced thermoelastic spectroscopy (LITES) has extremely high sensitivity and offers non-contact measurement, attracting extensive research ...
