The principle and maintenance method of laser ranging sensor are revealed

2021.12.28

As one of the most widely used ranging instruments, laser ranging sensors play a very critical role in various fields. We must also want to know the principles and maintenance methods of laser ranging sensors. The following small side combines years of experience to explain the principles and maintenance methods of laser ranging sensors.

1. The principle of laser ranging.

Laser ranging sensor: It is a sensor that uses laser to accurately measure the distance to a target. The laser rangefinder shoots a very thin laser beam to the target, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from emission to reception of the laser beam and calculates the distance from the observer to the target. Laser rangefinder is currently the most widely used rangefinder sensor.

2. The plane of the object must be perpendicular to the light.

Usually precision distance measurement requires the cooperation of total reflection prisms, and the house measurement rangefinder directly uses smooth wall reflection measurement, mainly because the distance is relatively short and the signal intensity of light reflection is large enough. You can know that it must be vertical, otherwise the return signal is too weak to get an accurate distance.

3. The object plane can be measured as diffuse reflection.

Thin plastic plates are usually used as reflective surfaces in actual projects to solve the serious problem of diffuse reflection.

4. The accuracy of the laser ranging sensor can reach an error of 1mm, which is suitable for various high-precision measurements.

Issues that should be paid attention to when using laser ranging sensors: Laser ranging sensors cannot directly measure the human eye to prevent harm to the human body. At the same time, the vibrator generally does not have a waterproof function, so it is necessary to pay attention to waterproofing. The latest Rio Potter laser rangefinder is mainly suitable for outdoor hunting enthusiasts in the United States, so its advantages are waterproof, anti-fog, and equipped with jungle branches and leaves. The laser has no anti-drop function, so the laser ranging sensor can easily damage the emitter.

Maintenance of laser ranging sensor.

1. Check the appearance of the equipment frequently, and clean up the surface dust, dirt, grease, mildew, etc. in time.

2. Clean the eyepieces. Use a soft dry cloth for the objective lens or laser emission window. Carve with a hard object to avoid damaging the optical performance.

3. This machine is a high-precision instrument that integrates optical, mechanical, and electrical. It should be placed carefully when using it, and it is forbidden to squeeze or fall from a high altitude to avoid damage to the instrument.
