We all know that pulse laser is widely used in daily life, so do you know where pulse laser is mainly used? Let's take a look at it from the perspective of Xiaobian.

Ranging and detection field

Most people's exposure to pulsed lasers should start with laser rangefinders and unmanned laser radars. Because in the pulse mode, the light goes out at once, and then the equipment calculates the distance according to the time when the light bounces back, which has better ability to resist environmental interference.

industrial process

Many people think that laser processing is high-power continuous output, but in fact, when doing fine processing, pulsed laser is better.

Like drilling small holes, film cutting, and some micro-machining, continuous drilling will scorch the material, and the pulse is different. It concentrates energy on one moment at a time, and the material is cleanly destroyed, but the heat is not easy to spread.

Imaging and scanning equipment

Some light sources, such as high-speed camera synchronous exposure, TOF depth camera and bar code recognizer, all like to use pulses.

The reason is very simple. As long as the laser and the detector jump at the same time, the image will not paste, and things can be swept in the dark.

Especially for TOF cameras, pulsed laser is standard, and the jump of tens of nanoseconds can make the depth calculation faster.

The above is the main application of pulse laser. If you still don't understand, please feel free to contact us.
