Abstract

Photon is an ideal carrier of quantum information, which can carry spin angular momentum and orbital angular momentum. In recent years, orbital angular momentum has shown great application prospects in quantum communication, quantum radar and other fields. It has gradually become a research hotspot in the field of detection. It is necessary to calibrate and measure the orbital angular momentum before it is applied to the detection field. Based on the interference principle and aperture diffraction theory, the measurement of orbital angular momentum is realized indirectly, and the experimental platform is built to verify part of the simulation results. It provides technical support for the subsequent implementation of quantum detection technology.
