WebThe FP interferometer has a periodic reflection and transmission spectra as seen in Section 6.2. Figure 6.56 shows the reflection spectrum of a GTI with an input grating 0.2 mm long and a rear grating length of 0.8 mm. With a refractive index modulation of 1.75 × 10 −3 mm, an eight, near identical channel dispersion compensator can be ... WebThough EUV and x-ray FPM systems significantly enhance the resolution down to sub-100 nm, they are limited for efficient implementation of FP optics in reflection mode for high angle illumination ...

Meanwhile, the two reflection surfaces R 1 and R 3 can also form an FP cavity (C 3 ) with a cavity length that is ... WebAn optical etalon (also called Fabry–Pérot etalon) was originally a Fabry–Pérot interferometer in the form of a transparent plate (often made of fused silica) with parallel reflecting surfaces ( solid etalon ). However, the term is often also used for Fabry–Pérots consisting of two mirrors with some air gap in between ( air-spaced ...
WebMar 1, 2024 · The absolute temperature is obtained by measuring the spectra of the FP reflection fringes at two different pressure levels, which is independent of the cavity length. Therefore, even if the enclosure (a glass tube in this case) of the air in the FP cavity were to change its length or undergo permanent deformations at high temperature, it would ...
