Abstract

We present a novel technique for the application of stroboscopic additive TV-holography to the measurement of vibrations using temporal phase-shifting. Based on a previous concept - contrived and developed by the same authors - that used two illumination pulses within each vibration cycle and interpulse phase modulation at the same rate that the vibration of the object, this new technique implements and analogous phase modulation scheme but between two swiftly alternating bursts of single pulses with different phase within each video frame, rather than using true double-pulses, thus allowing quantitative measurements to be performed with stroboscopic illumination keeping the characteristics of stability and temporal resolution of the double-pulse additive stroboscopic technique but with the additional benefit of reaching high vibration frequencies with low bandwidth phase modulators.
