China's 35th Antarctic expedition team carried a "super Laser pointer" that will launch lasers to this window to detect the "middle and high-level (75 km to 110 km) atmosphere" of the polar region. Lidar is an active optical remote sensing detection ...

Semiconductor lasers have strict requirements on working conditions, and improper working or storage conditions will cause rapid deterioration of performance and even failure. Therefore, the laser drive power supply that makes the laser work normally ...

Although the Laser pointer on the market have reduced the power to a large extent, the eyes, especially the eyes of children who are still under development, are very fragile. When the laser is directly shot into the eyes, it may burn the children's ...

The laser pointer is widely used in daily work and life. It is used as an indicator when explaining PPT in class, or as a marker for accurately indicating buildings from a long distance, or as a cat-playing artifact for people who play cats. The high ...

The Green laser pointer is a kind of laser pointer. It is often called a "finger star pointer". The internal semiconductor laser is a kind of LED. The front end is equipped with an optical lens for focusing. For astronomy enthusiasts, it is a commonl ...

The current projector and large screen are widely used, but the traditional keyboard and mouse-based human-computer interaction interactively bond the speaker next to the computer, and cannot realize the speaker and the audience. To solve this proble ...

The best option for astronomy is to use the maximum laser power the budget allows. Blue laser over 1000 MW is good, any green laser over 200 MW will also work. If you use 500 megawatts or more of green energy, you can get better sun exposure. In addi ...

Laser pointer is widely used in presentation. Users can be completely liberated from the computer. They are cheap, ready for equivalence, low power consumption and easier to handle PWM technology. Users don't have to put it next to the computer. The ...

The push-button matrix includes a laser push-button switch, and a laser diode and a laser push-button switch are connected to the switch. In multimedia teaching, most teachers use a laser pointer to display the content on the screen. In the event of ...

The laser pointer level can measure any object (including distant) angle or inclination, such as roof, building, column, mountain range, trees, etc. You can set any inclined angles and household appliances, the level of the equipment, and the refrige ...
