Summary: The object of the study is a laser vibrometer.
Subject of research – parameters and characteristics of a laser vibrometer.
The aim of the work is to develop a laser vibrometer for the study of aircraft engines at pre-flight testing and experimental studies.
Method of research – work with scientific and technical literature, creation of a mathematical model of vibrometer.
Existing methods of measuring vibration and in more detail theoretical bases of laser vibrometry, possibilities and features of laser vibrometer construction are considered.
As a result of the work, a mathematical model of a laser Doppler vibrometer, a structural diagram of a laser vibrometer was developed, and a model of an automated system of laser measurement of vibration of an aircraft engine was proposed, which allows us to construct a color dependence of the vibration level on a three-dimensional model of an airplane engine.
On the topic of the master's dissertation, theses were published in the framework of the student's scientific seminar "Scientific developments of RTF 2018" entitled "Contactless Doppler Vibration Measurement for the Study of Aircraft Engines".

Keywords: vibration, measurements, laser, automation, experimental research, vibration velocity, vibro displacement.


The work consists of:  70 pages of explanatory note and 2 appendix
