This scheme investigated the necessity of pulsed laser holographic interferometry (PLHl) through the use of flexible optical fiber elements for, the objects in enclosed system or otherwise inaccessible, poisonous environments. In Sec. II, the transmission characteristics, and the merit and demerit of the mono- and multi-mode optical fiber for pulsed laser were described. The paper indicated the advantages of -using multimode optical fibers in PLHI, simultaneously, two types of optical fiber system were presented. And finally in Sec. IV, the experimental results and conclusions were presented.
