Description

technical field [0001] The invention relates to the field of laser ranging, in particular, the invention relates to a laser emitting circuit, a laser receiving circuit, a distance calculation circuit, a power supply and equipment thereof. Background technique [0002] The laser rangefinder is an instrument that uses laser to accurately measure the distance of the target. When the laser range finder is working, it emits an elliptical cone-shaped laser beam to the target, and the photoelectric element receives the laser light reflected by the target. The timer measures the time from the launch to the reception of the laser beam, and calculates the distance from the observer to the target. The semiconductor laser rangefinder has the advantages of light weight, small size, low power consumption, and simple operation. The electronic circuit of the semiconductor laser rangefinder in the prior art also includes a laser emitting circuit, a laser receiving circuit and a mainboard ci...
