TWO DIMENSIONAL FIBER OPTIC INTERFERENCE THEORY
|
Abstract:
The output optical field interference characteristics formed by the ends of three HiBi single mode fiber is analyzed in this paper.We have established a simple theory model of two dimensional fiber optic interference.Under the condition of first order approximation,the intensity distribution formula of the two dimensional fiber optic interference field is deduced.The spatial frequency properties of the interference optical pattern are analyzed by two dimensional Fourier transformation method.Finally,related experiment results are given.
