HOLOGRAPHIC METHOD OF LIFTING HEIGHT MEASUREMENT ABOVE OBJECT SURFACE WITHIN EARTH'S ATMOSPHERE Russian patent published in 2017 - IPC G01C5/06 

FIELD: measurement technology.

SUBSTANCE: invention relates to methods of measuring lifting height above object surface within Earth's atmosphere. In holographic measuring method of lifting height above object surface as device sensitive element, implementing method of measurements, resilient sensitive element is used in form of corrugated membrane box or in form of bellows, which inner volume is filled with vacuum or gas under known pressure. Measuring instrument with resilient sensitive element is displaced in height to level, which height is calculated by holographic interferometer with semi-reflecting Fourier hologram, forming interference pattern, based on which parameters analysis value determining of resilient sensitive element shape change (surface displacement value) relative to initial position, caused by effect of changed atmosphere pressure on resilient sensitive element taking into account of its temperature, based on obtained result calculating measuring instrument resilient sensitive element lifting height relative to object surface.

EFFECT: increasing sensitivity and accuracy of lifting height measurements above object surface within Earth's atmosphere.
