A Research Of Polarization Measuring Based On Virtual Instrument

After the laser appears, with the rapid development of laser technology, The ancient optics has already advanced into the front of modern science technology relied on its dazzled development speed, incessantly emerging research results and great potential of itself. The technology of light polarization as the new branch of optics discipline, have been permeated and expanded to each domain of science technology and the applications, developing to be a unique emerging technology.The technology of the polarization measuring is the foundation of polarization application. The scope of polarization applications has widespreaded day by day since half century, people are paying more and more attention to the characteristic of polarization, and the methods of polarization measuring are also unceasingly developing and improving. However, the common system of polarization measuring often stresses on the design and analysis of rays path, lacks fast and convenient plan of hardware design as well as the method of software development which is rich, extendibility and strong.Therefore, this article take the method of phase delay modulation as the measuring principle, integrate data acquisition system by the monolithic, complete the processing and the demonstration of the metrical data based on the reliable LabVIEW platform. At last developed the system of polarization measuring based on visual instrument, provided a reliably, simple, the quick plan for the high speed and the precise state of research of polarization measuring.
