Abstract: We report a theoretical study about length measurement with polychromatic vortex beam in Mach-Zehnder (MZ) interferometer. The interference results show gear shapes as orbital angular momentum interference. According to the gear shape, we can predict the length difference explicitly. Our results suggest implicit measurement can be achieved with this method. [ABSTRACT FROM AUTHOR]
