In industrial applications, we often use laser ranging sensors because they can accurately estimate the distance to the target through very weak optical signals. In addition, it can record and process the time from the light pulse sending to receiving back, so as to measure the target. So, what problems should we pay attention to when using laser displacement sensor?
First of all, check before use to avoid the failure of the laser displacement sensor itself. If the laser ranging sensor itself has failed, or has been hit violently or refitted without permission, the ranging result may be incorrect. Therefore, when using the laser ranging sensor, it is necessary to pay attention to the inspection, and then use it after confirming that the sensor is normal, so as to avoid the error of the detection results.
Secondly, when using laser displacement sensors, do not put strong light sources or reflective objects on the surface, and pay attention to protect your health. Although everyone needs to obtain accurate distance measurement results, everyone should also pay attention to protecting their health. Therefore, when measuring the distance of an object using a laser ranging sensor, pay attention not to direct it at a strong light source, or a metal, mirror, prism or other surface that can emit light, otherwise, the operator's eyes are vulnerable to the damage of reflected light.
Finally, pay attention to avoid measuring the surface of inappropriate objects. Use laser ranging sensor to measure the distance of inappropriate objects, and the measurement results may be inaccurate. Therefore, in order to obtain ideal data results, it is recommended to avoid some inappropriate surfaces, such as rough surfaces; Transparent surface; Wet, smooth or high-gloss surface, etc.
In order to obtain accurate ranging results, we should not only use the widely acclaimed laser ranging sensor, but also pay attention to the inspection before using the laser ranging sensor, so as not to use the faulty sensor to cause ranging error. In addition, it should also be noted that the sensor should not be aimed at the strong light and mirror reflector, so as not to cause damage to the eyes.
