The numerical results denoted: in a cylindrical shell, the typical ultrasonic guided wave is Lamb wave like in a thin plate and the S0 mode is the fastest transmitting and less dispersion of guided waves; the main features of the surface waves in a thick hollow cylinder are three kinds of waves-- the surface skimming longitudinal wave, head wave and the Rayleigh wave, the first Rayleigh pulse`s polarity changes gradually with the propagating angle increment, and reverses one time from 0o to180o; if neglected the diffraction effects and only considered the dispersion effect, the polarity of the first Rayleigh pulse is only determined by the angle between the source and the detection point, and not related to the size of the specimen.

So when the wavelength of the incident light changes, only the position of rhomb-type retarder need to be changed to allow the light to represent oblique incidence in the front of rhomb, and then selecting suitable incident angle can compensate the dispersion phase deviation, and make the same rhomb possess standard λ/4 phase retarder under all different wavelengths.
