Abstract

Method for optical pressure measurement of a gas in a closed container by directing a radiation of a radiator through the container and measuring the transmitted radiation by a detector, wherein the radiation of the radiator covers at least one first wavelength range in which there is an absorption of the radiation by the gas, the intensity of the transmitted radiation is detected in a second wavelength range by the detector, wherein the second wavelength range overlaps at least partially with the first wavelength range, and an accumulated intensity of the detected radiation in the second wavelength range is assigned to a pressure of the gas.
