z(t
z(t
Δφ = 2π/N - величина фазового сдвига между сигналами ЛДВ в соседних периодах;
А - константа, определяемая конструкцией прибора,
а на границах интервалов результаты сшиваются с учетом непрерывности.A method of measuring the periodic law of motion of a vibrating surface using a laser Doppler vibrometer, including the formation of an array of zero level points, characterized in that the initial phase of the LDW signal is changed in accordance with the step law from 0 to 2π for N periods of vibration, in each period, the zero level intersection points are fixed by the electric signal LDV and within each interval between adjacent intersections of the zero level, step-by-step calculation of z (t) values at these points is carried out according to the formula
z (t
z (t
Δφ = 2π / N is the magnitude of the phase shift between the LDW signals in neighboring periods;
A is a constant determined by the design of the device,
and at the boundaries of the intervals, the results are stitched together with continuity.
