ОПИСАНИЕ ВЫПУСКАЕМЫХ ИЗДЕЛИЙ:

Installation for measuring the parameters of the propagation of ultrasonic waves in solid media.
The installation is designed to measure the attenuation coefficient αL of longitudinal ultrasonic waves, propagation CL velocity, longitudinal ultrasonic waves, and group propagation CS velocity of shear ultrasonic waves in solid media.
The basic difference of the developed installation from installations of a similar purpose is the use of broadband contactless means of generating and receiving ultrasonic waves created on the basis of capacitive transducers with a thin-film dielectric. The acoustic signal generator is made using a capacitive transducer operating in the mode of excitation of ultrasonic waves, and the receiver is a capacitive transducer in the mode of receiving ultrasonic waves.

Capacitive transducers with a thin-film dielectric provide generation and reception of ultrasonic signals in a wide frequency band. The operation of converters in the frequency band up to (0.1 - 500) MHz has been experimentally confirmed by studies.
The use of capacitive transducers ensures the absence of acoustic contact between the transducers and the object under study, thus excluding the influence of the acoustic contact (intermediate layer between the transducer and the object) on the measurement result.

Capacitive transducers with a thin-film dielectric with a diameter of 20, 10, 5 mm are manufactured at our enterprise. They are easy to use, have long life and high performance.

  • "A method of stabilizing the frequency of laser radiation and a laser with a stabilized frequency." The method is applicable to dual-frequency lasers. In contrast to the known methods of stabilizing the frequency of laser radiation, the proposed method does not involve the application of additional optical devices, that significantly improves the quality of stabilization and the operating characteristics of devices implemented using this method. In this case, the relative long-term instability is expected to be about 10-11, and the relative short-term instability is expected to be about 10-14.
