FIELD: measurement technology. ^ SUBSTANCE: proposed method is used for enhancing accuracy of laser interferometers (1,2) in measuring the distance, for example. Proposed method includes measurement of temperature of air along entire path of laser beam 3 radiated by laser interferometer through measurement of sound velocity 5 running over the same path; magnitude thus obtained is used for calculation of correction dependent on air temperature to magnitude of measured distance. ^ EFFECT: enhanced accuracy of measurements. ^ 9 cl, 3 dwg |
