  • Publication number: 20230288542
    Abstract: Methods, drive circuits, and lidars for laser emission control are provided. The drive circuit is configured to be coupled to a laser device and an energy storage unit, and includes a drive unit, a switch unit, and a detection unit. The energy storage unit includes a first terminal coupled to the laser device and the switch unit. The energy storage unit also includes a second terminal grounded, and forms the voltage supply path with a supplied voltage and the switch unit to perform charging based on a switch signal of a second control terminal, and to perform discharging based on a laser emission trigger signal of a first control terminal. The detection unit is configured to detect a signal of the first terminal of the energy storage unit during discharging and generate a corresponding state feedback signal based on a comparison of the signal with a preset threshold.
