The invention has particular utility in the training of football or soccer players. The device further includes the capability of adjusting the horizontal base portion and vertical upright portion such that the structure may be folded down onto itself for ease in portability, or for storage.

The invention provides an optical phase device, method and system. The optical phase device consists of a transparent dielectric substrate, a multilayer stack of dielectrics and a buffer layer. The refractive index of the transparent dielectric substrate, the multilayer stack of dielectrics and the buffer layer are all larger than that of the external medium. For the wavelength of the incident beam, the optical phase device has a phase variation in the angular range [α, β] and the critical angle for total reflection on the interface between the buffer layer and the external medium adjacent to the buffer layer is γ, γ<β. The optical device has both low loss and large phase variation, which leads to a large Goos-Hanchen shift. As a dispersion compensation component, it can produce larger, tunable dispersions, and different dispersion compensations can be obtained by adjusting the operating angle or parameters in the structure.
