The laser ranging sensor adopts the phase method laser ranging technology, which uses the frequency of the radio band to modulate the amplitude of the laser and measure the phase delay generated by one round-trip measurement of the modulated light, and then convert the phase delay represented by the wavelength of the modulated light. Distance, that is, the time it takes for light to travel back and forth by indirect methods.
FAQ
1. What is the difference between a laser measuring sensor and a laser rangefinder?
The biggest difference lies in the processing method of the measurement data. After collecting the data, the laser ranging sensor can record the data of multiple measurements and transmit it to the display for analysis, while the laser range finder can only display one set of data without recording. function and transmission. Therefore, laser ranging sensors are used in industry, and laser ranging can be used in life.
2. Can the laser ranging sensor be used for car collision avoidance?
Yes, our high-frequency measurement sensors can measure and monitor in real time, sense the distance between the front and rear, and help the car avoid collisions.
