В статье рассмотрена методика исследования стохастических или гармонических колебаний элементов контактных устройств в присутствии шума, основанная на применении лазерной голографической интерферометрии для конструкций. Восстановление амплитуд вибрации поверхности из ее голографических интерференционных диаграмм сложная и непрямая процедура. Неопределенность при восстановлении интерференционной диаграммы будет мала, когда диаграмма интерференционных полос строится при правильных условиях, и тогда интерферограмма будет легко поддаваться интерпретации.
In this article the technique to study stochastic fluctuations or harmonic elements of contact devices in the presence of noise, based on the application of laser holographic interferometry for construction. Restoration of the amplitude of vibration of the surface of its holographic interference diagrams a complex and indirect process. Uncertainty in the reconstruction of the interference diagram is small, when the chart is drawn on the fringe right conditions, and then the interference pattern will be easy to interpret.
