【Abstract】 Holographic lens arrays and elliptical zone plates are fabricated on holographic plate and photoresist by using interference of the 1st order diffraction and the 2nd order diffraction beams from ion etching Fresnel zone plate obtained by electronic beam scanning and deep ultraviolet lithography techniques. The experimental results of focusing and images produced are given.更多还原
