摘要: This paper proves a new theorem on the relationship between optical field Wigner function's two-parameter Radon transform and optical Fresnel transform of the field, i.e., when an input field ψ( x') propagates through an optical [ D( -B) ( -C) A] system, the energy density of the output field is equal to the Radon transform of the Wigner function of the input field, where the Radon transform parameters are D,B. It prove this theorem in both spatial-domain and frequency-domain, in the latter case the Radon transform parameters are A,C.

Abstract: This paper proves a new theorem on the relationship between optical field Wigner function's two-parameter Radon transform and optical Fresnel transform of the field, i.e., when an input field $\psi\left( x^{\prime }\right) $ propagates through an optical $\left[ D\left( -B\right) \left( -C\right) A\right] $ system, the energy density of the output field is equal to the Radon transform of the Wigner function of the input field, where the Radon transform parameters are $D,B.$ It prove this theorem in both spatial-domain and frequency-domain, in the latter case the Radon transform parameters are $A,C.$

Key words: Fresnel transform, two-parameter Radon transform, Wigner function
