Precision measurement

      The goal of precision measurement is to explore new methods and measurement mechanisms, to measure the measurement accuracy that can not be achieved by traditional methods, or to measure the physical parameters of interest, such as temperature, electric field, and magnetic field more easily and efficiently. We have made a series of papers on APL, OL, and other papers by exploring the new methods of accurate measurement of temperature, angle and magnetic field by using the properties of orbital angular momentum light around the fundamental physical quantity and high precision.
