| The accurate monitoring of the growth of rape and the related data of crops can not only provide an important source of information for the government,but also provide an effective basis for the study of the growth of crops and the increase of yield.The exact information transmitted to the processing stage of rape will encounter all kinds of disturbances,which will also lead to distortion or partial distortion of the information.It is well known that various kinds of information have been obtained by various sensors to detect rape.With the development of technology,light detection has the least damage to rape,especially the information monitoring of the area of the leaf and the canopy of the rape.This paper also studies the characteristics of optical information transmission.At the same time,the research shows that the transmission of optical information is more accurate in light information in the optical lattice medium.It also discusses the loss problem of optical information and the method of making up the loss in the process of media transmission.The condition of the formation of the information optical solitons and the state of the stable transmission are analyzed theoretically.The main work is as follows:First,we derive the general nonlinear Schrodinger equation for information transmission in the medium,and analyze the conditions for the formation and transmission of optical solitons.Second,the transmission equation of the information in the optical lattice is analyzed,and the change process of the light information potential function and the condition of forming the soliton transmission are discussed from the analytic direction by the variational method.Third,by using the MATLAB and Fu Liye transform methods,the characteristics of optical information transmission in the light lattice are simulated and analyzed.By changing the modulation depth and cycle parameters of the optical lattice,the control characteristics of the optical information transmission in the optical lattice are analyzed,so as to select the good parameters for the lossless transmission of the optical information. |
