  • Piezooptical measuring transducer
    Patent number: 4010632
    Abstract: A piezooptical measuring transducer comprises two light sources connected to a square-pulse generator so that the luminous fluxes of each light source pass alternately through a polarizer common for both fluxes, phase-shifting plates individual for each flux, an elastic element common for both fluxes, sensitive to variations of mechanical stresses therein caused by changes in the measurand, an analyzer common for both fluxes, all placed in that order downstream of the light sources across the fluxes, the latter being alternately incident upon a photocell. The phase-shifting plates are oriented so that their axes of maximum velocity of light propagation are perpendicular to each other.

  • Sensitive element of piezooptic measuring converter
    Patent number: 4002934
    Abstract: A sensitive element of a piezooptic measuring converter having an insert of a piezooptic material arranged between a foot and a base and rigidly attached thereto by means of their end portions constructed as a plurality of pins, which makes it possible to reduce thermal stresses in the insert more than 20-fold and thus reduce the temperature error of the piezooptic converter produced by these stresses.

  • Piezo-optic measuring transducer and accelerometer, pressure gauge, dynamometer, and thermometer based thereon
    Patent number: 3950987
    Abstract: A piezo-optic measuring transducer is disclosed herein and an accelerometer, a pressure gauge, a dynamometer, and a thermometer based thereon.The piezo-optic measuring transducer comprises two polarization-optical channels. Each of these channels includes the following components arranged in series downstream the luminous flux produced by a light source: a polarizer, an elastic element which is common to both channels and sensitive to stress variations therein caused by a variation in the measurand, an analyzer, and a photocell. Both channels are provided with a means for varying the intensity of the luminous flux incident upon one of the photocells which intensity variation is opposite in polarity to that in the luminous flux incident upon the other photocell. Both photocells are arranged in a differential relationship with the difference in the electrical signals produced thereby being representative of the measurand.
