What Are The Applications Of Semiconductor Lasers On Roads?

The notable characteristics of Semiconductor Lasers generators include ten major characteristics such as stability, modulation, life characteristics, price characteristics, efficiency characteristics, volume characteristics, power consumption characteristics, weight characteristics, threshold current characteristics, and temperature characteristics. You never imagined that so many semiconductor lasers have been used around us on the road alone. Similarly, it is hard for us to imagine how many epoch-making innovative breakthrough applications semiconductor lasers can develop in the future. Let us wait and see.

1. Application of semiconductor lasers in road surface pothole scanning

The potholes on the road surface must be the nemesis of everyone present when driving fast. The road surface conditions cannot always be found and repaired in time. Now, there is a very good decisive solution to this situation. Using the same principle technology as machine vision, the same It is based on the semiconductor laser line laser and the combined application of triangulation. The data is obtained by scanning the road, and the road surface information is digitized. , It can also meet the scanning detection of various traffic roads such as railway tracks, tunnels, and airport roads.

2. Highway warning application of semiconductor lasers
You may have seen it before. A row of green laser spotlights will be installed on the high-speed gantry in various places. This is also the application of semiconductor lasers on expressways. The function is very simple, it is to warn distant vehicles to pay attention to control the speed , The cool lights also stimulate the pupils, giving drivers a temporary sobriety and refreshing effect.

3. Semiconductor lasers road lighting application
The application of lasers in the lighting market continues to expand, so that automotive laser headlights are no longer limited to high-end vehicles, and will be further popularized to vehicles of various specifications and purposes, using semiconductor lasers as the main light source. Instead of using laser directly, further adjustments are required. There are currently two options:
(1) Combining laser light, the red, blue and green three-color laser light is combined to obtain white laser light, and further scattered to obtain soft white light to illuminate the road.
(2) For color conversion, only a semiconductor laser with blue light is used to irradiate fluorescent substances of various colors to convert white laser light, but the fluorescent substances will be consumed in this way, and fluorescent substances need to be supplemented later to meet the long-term road lighting of automobiles.

4. Application of semiconductor lasers road obstacle detection
Everyone can think of the two keywords of road + obstacle detection, that is, the very popular unmanned driving, which does not need too much introduction, through the combination of laser and artificial intelligence, the vehicle can automatically follow the road on the road Vehicle form, according to the form of traffic regulations, always detect road vehicles, pedestrians, obstacles, etc. within the radius around itself, and make timely avoidance.

5. Application of semiconductor lasers to assist pedestrians to cross the road
The use of semiconductor lasers on road zebra crossings is still a very novel application. Presumably few people know about it. It has recently been seen in the news "Street Crossing Artifact", "Laser Pile" Zebra Crossing Appears on the Street" and "Laser Zebra Crossing Put into Use". In road sections without sidewalk lights and traffic lights, such as Huancheng Road and other express road sections, the lights at night have many visual blind spots under the cover of big trees, and accidents are prone to occur. From the start, multiple red lines are lit on the feet, and red lights are laid on the sidewalk to remind driving vehicles that someone is passing by in a super conspicuous way.
