GEAR TESTING CHARACTERISTICS OF SEISMIC-ACOUSTIC TRANSDUCERS

摘要

seismoacoustics. SUBSTANCE: optically transparent prism with two parallel semitransparent mirrors is mounted in addition into gear testing characteristics of transducers. Reference mirror, optical quantum generator and photodetector are fixed on both sides of prism. Acoustically transparent plastic element is acoustically insulated from lid of gear. Gas laser with monochromatic radiation whose wave length satisfies preset measurement precision is used in the capacity of optical quantum generator. EFFECT: enhanced authenticity of determination of characteristics of seismic-acoustic transducers. 3 cl, 1 dwg
