Off-axis illumination (OAI) technology is widely used to enhance resolution for deep ultraviolet lithography. The realizing methods of OAI include geometrical optics method and physical optics method. However  the former has the disadvantage of weak intensity distribution controlling ability  and the latter introduces simulation errors evidently when dealing with near field diffraction propagation. A diffractive optical element (DOE) designing method using plane wave angular spectrum theory is presented in this paper. Several kinds of OAI modes at near field away from DOE can be realized  and simulation errors and the size of illuminator are also reduced. According to studying the relationships of the sampling point distance of DOE  light beam propagation distance  and the structure of the beam shaping unit  a method of determining the designing parameters is discussed. Using this method  several illumination modes are realized  and simulation results show that all diffraction efficiencies reach up to 84%. The method of DOE manufacturing is analyzed at last  and it is proven to be feasible. 2010 SPIE.

The main feature of the compound diffractive telescope is the combination of diffractive optics with compound structure arranged eyepieces. In this paper  a design of the compound diffractive telescope is firstly introduced  and a 4.2 FOV is obtained with one primary lens and twenty-one eyepieces. Secondly  image characteristic of different channels is analyzed with the design wavelength in ASAP  and one modified phase function model of diffractive optical element is introduced to analyze the MTF curves for 0 FOV  which provides a more accurate prediction of the performance of the system. Then the system is tested by the star image test  and the diffraction limit images are got within 2 FOV. And finally  two pictures taken from the adjacent FOV proved to be able to be spliced together. All the results above demonstrate that a good performance of the compound diffractive telescope. 2009 SPIE.
