| titleOfInvention | Interferometric pressure sensor |
| abstract | A pressure sensor having two chambers each filled to a predetermined pressure with a gas of high-refractive index and sealed. To measure pressure the gas in one chamber is subjected to the pressures to be measured by changing the volume of the chamber by a bellows. A beam of coherent light is split and passed through the two chambers and then recombined. A fringe counter detects fringe shifts caused by differences in the optical paths due to differences between the measured and predetermined pressures and provides a signal corresponding thereto. To measure differential pressure the gas in both chambers is subjected to the pressures to be measured. |
