The design of laser rangefinder PCBA

Laser rangefinder generally uses two methods to measure distance: pulse method and phase method. The process of pulse ranging is as follows: the laser emitted by the rangefinder is reflected by the measured object and then received by the rangefinder. The rangefinder also records the round-trip time of the laser. Half of the product of the speed of light and the round-trip time is the distance between the rangefinder and the measured object. The accuracy of measuring distance by pulse method is generally about + / - 1m. In addition, the measurement blind area of such rangefinder is generally about 15m.
