An integrated photodetector system is designed and manufactured, in which the photodetector array and the read-out circuits are integrated on the same silicon chip.

设计研制了一种集成光电探测器系统，它将光电二极管阵列及信号读出电路集成在同一硅芯片上。

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.

如果物镜与光盘之间的距离短于物镜的焦距，柱面透镜就会使在光电探测器阵列上的成像变成椭圆影像。
