Laser transceiver circuit and laser detection device

A laser detection device, comprising a laser transceiver circuit and a housing configured to mount the laser transceiver circuit, wherein the laser transceiver circuit comprises:

• a control module, configured to output a first pulse signal;
• a receiving module, connected with the control module, configured to receive the first pulse signal, and output a second pulse signal based on the first pulse signal, and determine a receiving start time of the receiving module based on the second pulse signal, wherein the receiving module starts to receive an echo signal reflected by a target object from the receiving start time;
• the control module is further configured to receive the second pulse signal, and output N third pulse signals based on the second pulse signal, wherein N is an integer greater than or equal to 1;
• and
• a transmitting module, connected with the control module, configured to receive the N third pulse signals, and transmit laser to the target object based on the N third pulse signals.
