Abstract
A prototype standard mercury manometer using a fringe counting laser interferometer to measure the differential height of the mercury columns has been built and successfully operated. The 10.6 μ wavelength radiation from a CO2 laser and specially treated manometer tubes have been used to reduce the effect of disturbances on the mercury surface so that reliable operation of the manometer is possible.This publication has 8 references indexed in Scilit:
