Description

In order to deform the wave surface of anoptical system by an amount ø (u, v), Phase Fresnel Lens is inserted in the pupil of the optical system.<br> By assuming 0_??_ø(u, v)<nλ, (u, v) region of the pupil is devided into m zones by Fresnel condition, <br> (k-1)λ_??_ø(u, v)<kλ; kth zone (k=1, 2, ……m), <br> where λ is the wavelength.<br> As the Phase Fresnel Lens is so made that it shifts the wave surface by the amount ø (u, v)-(k-1)λ in each Fresnel zone, the amount of its shift in each zone is smaller than λ, but this is quite equivalent to the deformation of the wave surface by ø(u, v) because of Fresnel condition.<br> Some properties of Phase Fresnel Lens are also discussed.
