The operation of a portable remote optoelectronic vibration sensor based on the autodyne effect in a laser diode is demonstrated. The sensor enables the measurement of vibration parameters: frequency (from 10 to 500 Hz) with a relative error of 0.08%, as well as amplitude, velocity, and acceleration with an error of 2.66-2.87%. Keywords: Vibration sensor, Autodyne effect, Laser diode, Remote measurement.
