Application of Piezoelectric Technology in Interferometry
Application of Piezoelectric Technology in Interferometry Interferometry technology is a measurement technology based on the principle of light wave interference. In the field of modern precision measurement, many measurement tasks are achieved by interference. For the solution of many measurement problems, optical interferometry is currently the only feasible method. Compared with the general optical imaging measurement technology, interferometry has the characteristics of large range, high sensitivity and high precision. With the continuous progress of science and technology, especially the emergence of laser technology and its application in the field of interferometry, the interferometry technology has been significantly improved in terms of range, resolution, and measurement accuracy. From classical optical techniques to adaptive optics engineering, the fields of application of modern interferometry techniques are constantly expanding. Modern image sensing and computer technology have also provided a huge boost to the development of interferometry, which has brought interferometric image reading and processing into a new era.
