Beschreibung
Zusammenfassung:	seismic prospecting, applicable in vibrodiagnosis. SUBSTANCE: the device has a rigid body, magnet, inertial mass, short-circuited coils, iris springs, fiber-optic measuring unit consisting of mirrors, light-emitting diods, lenses, optical connector/splitter, photodetectors, analog-to-digital converters, microprocessor, register, optical radiation sources. The specific feature is the fact of arrangement of the magnet inside the inertial mass. The short- circuited coils are positioned on the external side of the inertial mass are brought most closer to the center of gravity of the inertial mass. The open end of the light-emitting diode is coated with a semitransport mirror coating. EFFECT: enhanced accuracy of measurement of linear motion. 2 cl, 3 dwg
