The new lidar that uses the chip-based technology can use in the new nanotechnology. And it can also have the ability to operate in an anti-stealth role. The new very small-size lidars (laser radars) can make the next big step in nanotechnology. The lidar means optical-radar or long-range laser scanner. Sometimes it describes that it's optical area radar. (Wikipedia, Lidar). The lidar can use like radar. But it's a more multi-use system.
Lidar can see soft targets, like animals. And things like regular stealth systems cannot affect that scanner. The optical stealth suits also cannot resist the lidar scanners that are making 3D images of the surface.
Things like clouds cannot stop the lidar system. There is the possibility that lidar will use higher power to remove clouds and things like smoke away from its way. The lidar will rip water droplets from its route by using more power.
And that same system can also use in the very high accurate laser radars in long-range systems. The name of this new technology is chip-based OPAs (Optical Phrase Arrays). In Lidar magazine is the story, that OPAs are the next generation tools for lidar systems. (Lidar magazine/Why Optical Phased Array is the Future of Lidar for Autonomous Vehicles)
The old fashion OPAs have poor ray quality. But in the new design, those problems are solved. The description of that system is in the article on ScitechDaily.com. (ScitechDaily.com/ Smaller, Cheaper Lidar With New Chip-Based Beam Steering Device)
The difference between lidar and laser-tool is very small. The only difference between a laser sensor and a laser machine tool is the power. That the system uses.
And that makes lidar so powerful tool. When lidar sees things like small hills on the surface, it can increase its power. That makes it possible that this type of system can remove even atom-size anomalies.
The new lidar can make extremely thin laser rays that can observe the form of the nanomachines. The lidar will transfer a smaller energy load to the nanostructure than regular lasers. And that means it has a smaller effect on the complicated structures of the nanomachine molecules than so-called regular laser systems.
The lidar systems can use to scan the surfaces. That kind of ability makes it possible to find the anomalies from the things like graphene. And OPA-systems can also revolutionize graphene production.
The lasers can use to remove extra layers of carbon atoms from graphite. But the chip-based system makes it possible to create a laser system that covers larger areas. When a laser system detects an anomaly it can increase its power and remove that anomaly with pinpoint accuracy.
The laser system can vaporize graphite or carbon atoms of graphite layer by layer. In this case, the layer will be smooth. And graphite will be put to cover that layer. Then the laser starts to remove atoms layer by layer until there is only a 2D carbon atom structure left.
But the OPA:s can make many other things. It can form a group of separated laser rays, that can scan areas. And this kind of system can use to detect stealth fighters. The ability to use optical areas to detect stealth aircraft increases the abilities of the radars to detect many types of targets.
