  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

    如果物與光盤之間於物,柱面就會使在光電探測器陣列上成像變成橢圓影像。
  2. Spot diameters of just a few thousands of an inch can readily be attained with convenient short focal length lenses.

    用普通不難得到直徑只有幾十微米光點。
  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

    當選擇較大入射準直高斯光束束腰w _ 0和較f時,可以在平面上產生一個很小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
