MEASUREMENT METHOD OF PULSE PRESSURE, AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2013 - IPC G01L23/00 

FIELD: measurement equipment.

SUBSTANCE: receiving housing is made in the form of a stiff element with an opening passing the recorded disturbances, in which a source outlet and a light receiver inlet, or ends of optical fibres, which supply light from the source and to the receiver, are fixed. Modulator of intensity of recording emission is represented with the medium, via which that emission and measured pressure disturbance is spread.

EFFECT: providing the possibility of measuring quickly variable pressure pulses of arbitrary duration with wide-band spectrum without distortion as to amplitude and spectrum, non-sensitivity to vibrations and electromagnetic interference, simplifying the design of the device, increasing stiffness and stability in relation to external actions.
