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。If the objective lens is further away from the compact disk than the focal length of the object lens, then the cylindrical lens again creates an elliptical image on the photodetector array
如果物鏡與光盤之間的距離長於物鏡的焦距,柱面透鏡也會使在光電探測器陣列上的成像變成橢圓影像。Of course, if the disk is right at the focal length of the objective lens, then the cylindrical lens does not affect the image and it is perfectly circular
當然,如果正好處於物鏡焦距位置,柱面鏡就不會影響到光電探測器上的成像,因而會獲得一個完美的圓性影像。Advanced cooled quantum well infrared photodetector qwip
