Rotational Laser Doppler Vibrometry pt 2 of 3 - angular vibration measurement

This series of videos accompanies a laboratory exercise entitled Vibration Analysis of Rotating Machines - Rotational Laser Doppler Vibrometry in which Dr Ben Halkon, Senior Lecturer in the School of Mechanical and Mechatronic Engineering within the Faculty of Engineering and IT at UTS describes the nature and application of laser rotational vibrometry for the measurement of angular and torsional vibration. In this second of three video clips, the use the rotational laser vibrometer to make a measurement of angular vibration is described and the sensitivity of the instrument (in rad/s/V) to angular vibration can be determined by interrogation of the signal levels observed and the geometry of the test system (refer to the accompanying lab handout).
