초록
Electronic speckle pattern interferometry has many applications in science and engineering. Among these, vibration measurement is the area where ESPI has many advantages over other techniques. We developed a stroboscopic ESPI system to measure the harmonic vibration of a piece of copper tape attached to a circular hole structure. Figure 1 shows the schematic diagram of the stroboscopic ESPI system. (omitted)
