WebThis system employs a Fabry-Perot etalon as an object plane preprocessing filter. For mechanical simplicity and to add the possibility of object scaling, the object is actually imaged onto the etalon as shown. in Fig. 5. A Fabry-Perot etalon has a transmittance that is a function of illumination incidence angle. It can thus WebFor the use of the Fabry-Perot as a Filter, one can de ne the FWHM in angular frequency or cyclic frequency: ∆Ωres = c(1 R) nd p R (17) ∆ res = c(1 R) 2ˇnd p R (18) 2.1 Fabry-Perot Cascade Let us assume that the thinnest practical Fabry-Perot to be of 100 m thickness.

WebA Fabry-Perot cavity (or interferometer, or etalon) is an optical system that has two partially transmitting mirrors facing each other, between which light coming in through one mirror is reflected multiple times before it exits the opposite mirror. These cavities may be designed in various ways. The Model 240 Spectrum Analyzer is a confocal ...
WebThe Fabry-Pérot interferometer was developed in 1897 by the French physicists Charles Fabry (1867-1945) and Alfred Pérot (1863-1925).
