  1. If the objective lens is closer to the compact disk than the focal length of the object lens, then the cylindrical lens creates an elliptical image on the photodetector array

    如果物鏡與光盤之間的距離短於物鏡的焦距，柱面透鏡就會使在光電探測器陣列上的成像變成橢圓影像。
  2. Spot diameters of just a few thousands of an inch can readily be attained with convenient short focal length lenses.

    用普通的短焦距透鏡不難得到直徑只有幾十微米的光點。
  3. When a larger waist w of the incident gaussian beam and a shorter focal length / of the lens are chosen, we can obtain an extremely - small dark spot size of the focused hollow beam, even approach the diffraction limit

    當選擇較大的入射準直高斯光束的束腰w _ 0和較短的薄透鏡焦距f時，可以在焦平面上產生一個很小的dss （或束半徑r _ 0 ） ，甚至可以接近衍射極限。
  4. But the implementation of traditional wfcs in an optical system is difficulty, so the applications is limited. in 2000, a novel wfcs comprising a distorted diffraction grating ( dgwfs ), simple optics and a single camera has been described by blanchard

    2000年， blanchard等提出了一種新型的波前曲率傳感器，它利用二次扭曲光柵和短焦距透鏡密接使用，來實現波前曲率測量。
  5. Numerical result illustrates that focal length becomes longer when incident wavelength becomes shorter, however the relationship between focal length and incident wavelength is n ' t absolute inverse ratio, it is that the increasing of focal length is faster than the decreasing of incident wavelength. at the same time the numerical result also show that scalar theory ca n ' t be used in the rigorous analysis of the dispersion property of subwavelength diffractive microlens

    然後研究了亞波長衍射微透鏡的色散特性，表明亞波長衍射微透鏡的焦距隨著波長變短而增加，但是波長與焦距之間並非簡單的完全反比例關系，而是隨著波長的減小焦距增加得更快，同時指出標量理論已不能準確分析亞波長衍射微透鏡的色散特性。
