Fabry-Perot-cavity-based refractometry without influence of mirror penetration depth

open access: yes, 2021
Assessments of refractivity in a Fabry-Perot (FP) cavity by refractometry often encompass a step in which the penetration depth of the light into the mirrors is estimated to correct for the fraction of the cavity length into which no gas can penetrate ...

The Short-Term Performances of Two Independent Gas Modulated Refractometers for Pressure Assessments

open access: yesSensors, 2021
Refractometry is a powerful technique for pressure assessments that, due to the recent redefinition of the SI system, also offers a new route to realizing the SI unit of pressure, the Pascal. Gas modulation refractometry (GAMOR) is a methodology that has

Spectral Domain Low- Coherence Interferometry for On-line Surface Inspection [PDF]

open access: yes, 2013
We present an on-line surface measurement technique based on spectral domain low-coherence interferometry (SD-LCI), which can obtain a one dimensional surface profile with just one shot.

Critical-Angle Differential Refractometry of Lossy Media: A Theoretical Study and Practical Design Issues

open access: yesInstruments, 2019
At a critical angle of incidence, Fresnel reflectance at an interface between a fronttransparent and a rear lossy medium exhibits sensitive dependencies on the complex refractiveindex of the latter.
