METHOD OF MEASUREMENT OF REFRACTIVE INDEX OF GAS IN TURBULENT FLOWS Russian patent published in 1997 - IPC

Abstract RU 2079834 C1

FIELD: measurement technology, interference refractometry. SUBSTANCE: calibration of interferometer of white light in measurement units of monochromatic light is additionally carried out directly before execution of measurements. Aids to compensate for optical difference of action are used and averaged positions of achromatic band are registered after stoppage of compensation actions and return of achromatic band into observation zone. EFFECT: expanded application field of method. 1 dwg
