ABSTRACT:
This invention provides a simple and easily manufacturable lens apparatus, a space variant phase shifter, which is one of the key components in an optical ambiguity function generator. The improved lens apparatus is a combination of conventional optics comprising a cylindrical lens and a spherical lens in which the spherical lens is of opposite sign than the cylindrical lens and of one half the power.
