Embodiment Construction
[0019] The present invention will be described in detail below in conjunction with the accompanying drawings. As a part of this specification, the principle of the present invention will be described through embodiments. Other aspects, features and advantages of the present invention will become clear at a glance through the detailed description.
[0020] Such as figure 1 As shown, a method of laser ranging, including a time-to-digital converter 2 for timing, an MCU1 for controlling the threshold of a high-speed comparator 3, a transmitting module for emitting laser pulses, and a receiving module for receiving laser pulses module, including the following steps:
[0021] (1) MCU1 sets the initial threshold value, and emits the first pulse to trigger the time-to-digital converter 2 to start counting.
[0022] (2) Send a second pulse at an interval of 500ns to trigger the transmitting module to emit laser light, and at the same time turn on the receiving module to receive the ec...
