| Abstract: | Avalanche photodiode(APD)is widely used in photo-detection because of its high interior gain. Based on the avalanche effect and operating principle of APD, it was used as receiving unit to capture the reflected wave of “cat eye” target, a receiving-magnifying circuit was designed. The experiment of this circuit has been studied. The results demonstrate that the detecting circuit can capture the reflected wave of “cat eye” target and the reflected wave signal contains timing info and distance info of the target, the target could be accurately located. The study will lay the foundation for the design of various laser active detection systems. |
| Keywords: | APD laser active detection “cat eye” target |
