A laser sensor is a sensor that uses a laser beam to measure the distance of a target object or detect the properties of the target object. Its working principle is based on the characteristics of the laser beam, including light scattering, reflection, absorption, etc. working principle: Laser emission: The laser sensor first generates a laser beam through the laser. Interaction between laser and target: After the laser beam irradiates the surface of the target object, various phenomena will occur, including reflection, scattering, absorption, etc. Signal reception: The sensor receives the light signal reflected, scattered or absorbed by the target object. Signal processing: The received signal is processed and may require operations such as amplification and filtering to extract useful information. Distance calculation: By measuring the time required from laser emission to reception, combined with constants such as the speed of light, the distance between the target object and th...
