The new stereo camera beats lidar.

 The new stereo camera beats lidar. 


Lidar or laser radar might be the eye of the tiger. Researchers are operating systems that do not use active radars to avoid jamming and radio radiation that can uncover observers. The problem with lidar is that the system sends laser beams that can cause eye injuries if there is damage in the lens of that system. Also in some cases, the active laser rays can make the lidar system very visible. The lidar can also be used as a laser communicator making the system a multi-use tool. 

But passive systems like low-light CCD technology using cameras that can point the cameras by connecting multiple pixels from both cameras can also be very accurate. Those camera systems can measure distances very effectively and accurately. Those CCD cameras can operate in almost total darkness. The AI-based software can interconnect those pixels from both cameras with extremely high accuracy.

It can used to detect aircraft, satellites, and ground objects. If the telescope uses the CCD-based stereo-imaging system it can measure distance to satellites accurately. This system is also immune to anti-radar stealth technology. 

And that kind of system can replace lidars. That CCD-based stereo camera is created for working in robot cars. However, the engineers can install the same system in all systems. That requires very accurate distance measurements. If artillery or some other military system uses that triangular passive optical rangefinder. That means the system will not send any kind of radiation. 

The passive detector and rangefinder make it impossible to locate the benefiting signals that the system sends. If the missile uses an optical passive camera-based homing system. The only thing that can detect it is radar and  IR signature. But those kinds of missiles do not alarm electronic surveillance systems. This kind of system can use an inertial navigation system until they see targets. And that thing makes them immune to jamming. In terminal sequence, those missiles can use an optical image-based target recognition system which gives it pinpoint accuracy.

MIT's tractor beam can make the new types of SASER systems possible

   "This chip-based "tractor-beam," which uses an intensely focused beam of light to capture and manipulate biological particles without damaging the cells, could help biologists study the mechanisms of diseases."(Interesting Engineering, MIT’s Star Wars-inspired ‘tractor beam’ uses light to capture, manipulate cells) MIT's tractor beam can make the new types of SASER systems possible. The tractor beam just hovers the nanoparticle in air or medium, and then the laser or some other electromagnetic system transports oscillation into those particles. The ability to make cells and other particles hover in the system makes it possible to create particles whose energy level or resonance frequencies are accurately calculated things.  That thing makes it possible to create things that transmit wave movement accurately and cleanly. This is one version of the use of a tractor beam. Modern tractor beams are like acoustic tweezers where sound waves lock the object in its cr

The new observations tell that the thunderstorms form gamma-rays. That could make gamma-ray lasers possible.

That could make gamma-ray lasers possible. The process has been observed by the NASA (Lockheed) ER-2 research plane, which is a modified U-2 spy plane. The gamma-ray formation in thunderstorms. Where lightning and electric fields release electrons that impact the air molecules and water droplets is an interesting thing. That thing opens the route to solving many mysteries.  "The general physics behind how thunderstorms create high-energy flashes of gamma radiation is not a mystery. As thunderstorms develop, swirling drafts drive water droplets, hail, and ice into a mixture that creates an electric charge much like rubbing a balloon on your shirt. Pos

Chinese innovations and space lasers are interesting combinations.

Above: "Tiangong is China's operational space station located in low Earth orbit. (Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft.  Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things.  In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion.  If we th
