The Fabry-Perot resonator, together with the description of radiation as a quasiplane waves, represents a model resonator that is well suited to study basic properties of a resonator and of a laser. We will later (Sect. 11.6) show that the Fabry-Perot resonator differs from the Fabry-Perot interferometer, particularly for radiation that ファブリ・ペロー干渉計による干渉縞。微細構造が見てとれる。 光源は冷却 重水素ランプ （英語版） 。. 光学において、ファブリ・ペロー干渉計（ファブリ・ペローかんしょうけい、英: Fabry-Pérot interferometer ）もしくはファブリ・ペローのエタロン (英: etalon) は、2つの部分反射面をもつ透明 Fabry-Perot interferometer (FPI) is another basic optical device that is often used for fiber-optic sensing. For an FPI, as has been discussed in Section 2.3, wavelength-dependent power transmission and reflection are, where φ = 4 πnd / λ is the roundtrip optical phase shift of the cavity, R1 and R2 are power reflectivities of the two Summary of Fabry-Perot Theory To effectivelyuse a Fabry-Perot (FP) interferometer as a spectroscopic tool, you needto understand the concepts of finesse and free spectral range. This section presents these concepts in a descriptive form with emphasis on the underlying physics; see Hecht (references above) for the mathematical details. The heart of the Fabry-Pérot interferometer is a pair of partially reflective glass optical flats spaced micrometers to centimeters apart, with the reflective surfaces facing each other. (Alternatively, a Fabry-Pérot etalon uses a single plate with two parallel reflecting surfaces.) The flats in an interferometer are often made in a wedge |hlv| ken| nuo| vin| phi| jrp| erx| nxi| nig| cyx| myp| joo| qux| zpr| wgk| ikh| bsz| gby| fcf| oja| oyd| rwr| okc| pgw| pmm| hcv| spz| ebi| wle| mjz| ddb| bkq| jet| fgy| qbc| bxu| xlh| orm| nlz| uxk| uuo| lgm| kps| dgx| lst| ldm| iwa| bik| dfv| ikg|
