What should I do if the laser pointer LD is damaged?
It is recommended not to exceed 30 seconds in summer. If you feel the green laser pointer becomes hot, do not use it immediately. Please wait for it to cool down completely. In winter, the green 532nm laser pointer may need to be warmed up for a period of time to reach the highest luminosity. After putting it in my pocket and heating it up, I put the battery in and used it again. Starry sky observation Do not keep the laser pointer on for more than 1 minute to avoid rapid aging and overheating to damage the laser pointer LD or module! The laser displacement sensor can make use of the high directivity, high monochromaticity and high brightness of the laser to realize non-contact long-distance measurement. Laser displacement sensor (magnetostrictive displacement sensor) is a new measuring instrument made by using these advantages of laser. Its appearance has greatly improved the accuracy and reliability of displacement measurement, and it also provides effective non-contact displacement measurement. Method of measurement.

After receiving the laser pointer, please charge the battery before using it. If the battery power is low, the light will be weak, this is not a product problem, please charge the battery or replace with a new battery. (When charging, the charger will light up red. When fully charged, the charger will automatically stop charging and light up green. Please take out the charger to avoid overcharging..) I am worried about leaving the laser-powered lithium battery for a long time, even if I don’t use it, and I should get into the habit of charging it once a month. The working principle of lidar is very similar to that of radar. Using laser as the signal source, the pulsed laser emitted by the high power laser pointer hits trees, roads, bridges and buildings on the ground, causing scattering, and part of the light waves will be reflected to the receiving of lidar. On the device, calculated according to the principle of laser ranging, the distance from the laser radar to the target point is obtained. The pulse laser continuously scans the target object, and the data of all target points on the target object can be obtained. After this data is used for imaging processing, Accurate three-dimensional images can be obtained.
