Research Progress of Applications of Optical Vortex in Micro- Measurement

涡旋光是具有螺旋型相位波前和相位奇点的光束,相位奇点处的相位不确定,而光强为零。携带非零轨道角动量的涡旋光在微测量方面具有广阔的应用前景。主要介绍了光学涡旋干涉术、光学涡旋计量术的工作原理和研究进展,并介绍了其他应用光学涡旋进行变形测量的研究进展。并对光学涡旋在该领域的研究和应用前景进行了展望。

Vortex beam has wave front screw dislocations and phase singularity. The core of the optical vortex has undefined phase and zero amplitude. Optical vortices which carry non- zero orbital angular momentum have potential applications in micro- measurement. The basic principle of optical vortex interferometer and optical vortex metrology are briefly summarized,as well as their progress. Other related research techniques are also introduced. A brief outlook about the future study and applications of optical vortex beams and optical vortices is discussed.
