ABSTRACT:
A Fourier transform lens system includes: a first lens group having negative power and a second lens group having positive power disposed at one side of the first lens group with the first lens group and the second lens group being arranged on a common optical axis. The first lens group includes two negative meniscus lenses each having negative power, and each of the negative meniscus lenses has a concave lens surface facing toward a concave lens surface of the other negative meniscus lens. The second lens group includes a positive lens having a convex lens surface facing toward the first lens group. The Fourier transform lens system satisfies the following conditions: (1) 0.1<R1R/f<0.4; (2) −0.4<R2F/f<−0.1; and (3) 0.1<d12/f<0.3. A holographic storage system using a Fourier transform lens system is also provided.
