Abstract:
A method, apparatus and optical device for detecting a relationship between an evanescent field and Goos-Hänchen shift, said method comprising: obtaining a potential field function of an evanescent field acting on total-reflection light according to physical meanings of a force function and the potential field function of light in the evanescent field (S 101 ); obtaining a wave function of the perturbed total-reflection light by means of the Schrödinger equation by combining with the potential field function of the evanescent field acting on total-reflection light (S 102 ); and comparing the wave function of the perturbed total-reflection light with a wave function of free total-reflection light with no action from the evanescent field, and determining a momentum gained by the total-reflection light under the action of the evanescent field, which is the same in nature as a momentum of the evanescent field (S 103 ).

Claim (Index 7):
The apparatus according to  claim 6 , characterized in that, the force function of light in the evanescent field is: F \u2192 = \u03b3 - 1 \ue8a0 [ 1 2 \ue89e \u03c9 \ue89e Re \ue8a0 ( \u03b1 ) \ue89e \u2207 w + Im \ue8a0 ( \u03b1 ) \ue89e Im \ue89e p \u2192 o ] wherein w = \u03b3 2 \ue89e \u03c9 \ue8a0 ( | E \u2192 \ue89e | 2 \ue89e + | H \u2192 \ue89e | 2 ) = w e + w m the energy density of the electromagnetic field; \u03c9 is an angular velocity; \u03b3=(8\u03c0\u03c9) \u22121  is the Gauss unit; for linearly polarized light, both the electric field and the magnetic field have the same degree of polarization, namely \u03b1 e =\u03b1 m =\u03b1; {right arrow over (p)} o  is an orbital momentum; {right arrow over (E)} and {right arrow over (H)} are respectively the amplitude of the electric field and the amplitude of the magnetic field; and w e  and w m  are respectively the energy density of the electric field and the energy density of the magnetic field.
