Features of a real Fabry-Perot interferometer are severely affected by surface irregularities. A new configuration, based on appropriately masking the plates, is proposed. Theoretical results show an increase in the finesse of as much as a factor of 10 as well as an increase in the contrast factor of as much as a factor of 100, while the luminosity-finesse product is preserved.

Abstract

Features of a real Fabry-Perot interferometer are severely affected by surface irregularities. A new configuration, based on appropriately masking the plates, is proposed. Theoretical results show an increase in the finesse of as much as a factor of 10 as well as an increase in the contrast factor of as much as a factor of 100, while the luminosity-finesse product is preserved. The case of nonnormal incidence is also considered, and the differences arising from that case are discussed.
