Query: Accurately measuring phase profiles of structured light in optical
  manipulation   Accurate phase measurement is highly desirable in optical manipulation driven
by structured light, since the phase profiles have a close connection with
optical force distribution, strongly affecting the capability of optical traps.
Here, we report a novel interferometric phase measurement technique for
accurately measuring the phase profiles of structured light in holographic
optical trapping system. The related experiments are performed, in which the
obtained phase profiles agree well with the designed phase profiles. It reveals
that the phase profiles of structured light can be accurately obtained.
Importantly, the fast switch between phase measurement and optical manipulation
experiment can be easily realized, which are strongly preferable in optical
trapping system. This study offers a promising way for accurately obtaining
phase profiles of structure light, which is very helpful for realizing optical
trapping with high performance.
