Development Of Optical Vortex Simulation System

The vortex beam has recently been attracting much attention due to its unique property in the phase factor,helical phase distribution structure,and each of the photons carries an orbital angular momentum.Extensive research on the vortex beam has been conducted as a potential special beam.The vortex beam can move the particles by transmitting the carried orbital angular momentum to the particles.Because of this special property,the vortex beam is applied in the practice of information coding,biomedical and optical tweezers manipulation.The main object of this paper is an integer order vortex beam.After a brief introduction to the vortex beam,its development history and application,a basic grasp of the vortex beam was shaped.According to the characteristics of the study object,the following study for mainly three aspects had been performed:(1)Based on the insight and analysis of the vortex beam,the theoretical basis of the vortex beam was studied.The single-slit diffraction study of the vortex beam and the circular diffraction of the partially coherent vortex beam were studied by simulation.The results shows that the influence of the parameters on the diffraction pattern and the intensity of the diffraction,which plays an important role to study the characteristics of the vortex beam.(2)After analyzed and studied the characteristics of the vortex beam,the intensity reorientation and separation can be realized by two vortex beams in the multiplexing communication system.The advantage of this communication system is to overcome the shortcomings of complex structures and less integration.The special properties of the non-coherent vortex beams using in the intensity multiplexing communication system application is an important research direction of vortex beams.(3)Combining with the research results of the diffraction performance of the vortex beam and the intensity reuse communication system,a visual interface was designed based on the visual programming method.The realization process of the research results is displayed and presented in the interface visualization,and the visual interface of the experimental result can be simulated by inputting the parameter size to be changed only in the input box of the interface.The visual interface has advantages of convenience,confidentiality and the characteristics of commercial development.
