Industrial laser rangefinders play an important role in the industrial field, mainly used for high-precision measurement and automation control. Industrial laser rangefinder accurately calculates the distance between the sensor and the target object by emitting a laser beam and receiving the laser signal reflected back from the target object, based on the time difference between the laser round-trip and the speed of light. This non-contact measurement method has higher accuracy and faster response speed compared to traditional contact measurement.
Industrial laser rangefinders are mainly based on time-of-flight (TOF) or phase difference methods for distance measurement:
Time of flight method: The laser rangefinder emits a short pulse laser beam, which is reflected back when it encounters the target object. The rangefinder receives the reflected laser signal and measures the time from emission to reception of the laser (time of flight), multiplied by the speed of light, to calculate the distance to the target.
Phase difference method: The laser rangefinder emits continuously modulated laser signals, which interact with the target object during propagation, resulting in phase changes. The receiver receives the reflected laser signal and compares it with the transmitted signal, measures the phase difference, and calculates the distance to the target based on the relationship between the phase difference and modulation frequency.
main purpose
