| Title: | An economical piezoelectric phase modulator for fiber optic sensors | Authors: | Lau, KS Wong, KH Chan, TL Yeung, SK |
Issue Date: | 1-Dec-1996 | Source: | Applied optics, 1 Dec. 1996, v. 35, no. 34, p. 6836-6838 | Abstract: | A homemade piezoelectric phase modulator for interferometric fiber optic sensors was fabricated using piezoelectric buzzers as strain elements. Six piezoelectric elements were embedded between the two halves of a bakelite cylinder split along its axis and secured tightly together again to form a cylinder. Single-mode optical fiber was then wound around the cylinder to complete the unit. Up to a frequency of 500 Hz, the phase shift produced by the modulator is linearly proportional to the amplitude of the applied voltage. The sensitivity of the phase modulator is about 3.6 rad/V and has a dynamic range of 1,000 rad, which is sufficient for most phase modulation purposes. | Publisher: | Optical Society of America | Journal: | Applied optics | ISSN: | 0003-6935 | DOI: | 10.1364/AO.35.006836 | Rights: | © 1996 Optical Society of America.
