1 October 1991 Four cases of engineering vibration studies using pulsed ESPI
Author Affiliations +
A diode seeded Nd:YAG pulsed laser is used in conjunction with ESPI to study targets undergoing resonant in-plane and out-of-plane vibrations. The Nd:YAG laser is capable of operating in a single- or twin-pulse mode. At a repetition rate of 50 pulses/sec, the single- and twin-pulse operations are used to create subtraction fringes, and the twin-pulse operation (at 50 twin pulses/sec) to produce additional fringes. Results are presented for phase determination from in-plane and out-of-plane subtraction fringes, and also results on noise reduction for additional ESPI fringe patterns.
