The printer market in 2018 has good news for consumers. Regardless of black and white laser printing or color inkjet printing, there is a very cheap laser pointer option to use original supplies-print a page for a few cents. Say goodbye to the histor ...

In a collaboration between the University of Aurges and the University of Southern Denmark, the researchers discovered a way to subtract individual quantum lights from laser pointers. This work was recently published in the Physical Review Letters. T ...

On May 9, 1962, the Massachusetts Institute of Technology conducted the first successful launch of light waves to the moon with a laser pointer and returned. Now, let's find out why the laser has so much energy that it can reach the moon! A laser is ...

The circulator is very important for optical routing in optical communication. However, they often require centimeter-level magnets, and these magnets are difficult to miniaturize for use in optical chips. Researchers at AMOLF, the University of Texa ...

Publishing specific prices for immediate delivery, like Ouster, helps build credibility. We believe Velodyne will make every effort to match Ouster's $ 12,000 price tag at some point in the future. But doing this in the future is not the same as bein ...

For flood imaging LiDAR, the light emitted each time is scattered throughout the field of view, which means that only a small part of the laser will be projected to some specific point. In addition, each pixel in the photodetector array must be very ...

Pacala points out several advantages of traditional rotary mechanical LiDAR designs. Among them, the most obvious advantage is its 360 ° field of view. We can install a lidar fixed on the top of the car to sense the surroundings of the car 360 °. I ...

The modern 3D (three-dimensional) LiDAR (Lidar) scanner was invented in the mid-2000s. But in recent years, the traditional belief is that Velodyne's design (installing 64 lasers on a rotating platform) will soon be eliminated by a new generation of ...

However, the actual reflective ability of the mirror is limited by the smoothness of the surface. Since there is no absolutely smooth mirror in the world, it is impossible to reflect 100% of the laser energy back. It will occur when the energy absorb ...

In order to ensure the safety of electricity use, electricians inspect the wires and cables every day. If foreign objects are found on the wires, they must be cleaned in time. In the past, electricians had to clean up at high altitudes. It was very d ...
