Tunable spatial filtering with a Fabry-Perot etalon - Virginia Tech
WebAmong these the Fabry-Perot interferometer (FPI) is a very popular option since it can be fabricated in different ways [19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35]. For … 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 impact factors 2020
