Vacuum measurement of He based on Fabry-Perot cavity and constant pressure reference
In order to reduce the uncertainty of the gas refractive index measurement device based on laser interferometry. A measuring method based on constant pressure reference point was proposed. Combined refractive index of reference point and variation of laser frequency measured by beat frequency, the r...
