Laser ranging sensor is a sensor that uses laser technology to measure and convert data. It is composed of lasers, optical parts, and optoelectronic devices. It can measure measured physical quantities (such as length, distance, vibration, flow, speed, etc. ) into an optical signal, and then use a photoelectric converter to convert the optical signal into an electrical signal. Through the filtering, amplification, and rectification of the corresponding circuit, the output signal is obtained, thereby calculating the measured value.

Compared with other sensors such as ultrasonic, infrared, and millimeter waves, laser sensors have incomparable advantages in terms of measurement accuracy, resolution, anti-interference ability, stability, and response speed. Therefore, when the measurement accuracy is high, such as 0.1mm, 0.01mm, or even 1um, laser ranging sensors are generally preferred.

The main advantages of laser sensors:

High precision and high resolution: Laser sensors can achieve very precise measurements and can meet application scenarios that require high measurement accuracy.

Strong anti-interference ability: The laser sensor has less impact on the external environment and can work stably under various interferences, such as strong light, climate change, reflection from surrounding objects, etc.

Good stability: The laser sensor has high stability and long life, is not easily affected by factors such as time and temperature, and can work stably for a long time.

Fast response speed: The measurement speed of the laser sensor is very fast, the measurement results can be obtained in real time, and it is suitable for high-speed movement measurement scenarios.
