Abstract
Possible use of double mode gas lasers for remote recording of small vibrations of distant objects has been studies. Vibrations of the amplitude approximately 10-3(lambda) ((lambda) is the emission wavelength) have been recorded at the distance up to 30 m in the frequency range up to several megahertz. The maximum sensitivity of one of the suggested methods of vibration recording has been estimated.
