Green light laser will travel in straight lines affected by wind?

The first to launch a bunch of active green light laser low energy ranging from the upper part of the aircraft pod, the coarse lock, provide location coordinates of missile; and then rotate the laser turret, which aimed at the target; then launch tracking laser beam and beacon illuminating laser beam to illuminate the target tracking, the laser beam on the contact missile, nose cone at the top of the missile with light irradiation, high resolution imaging sensors for missile imaging using reflection, further determine its position, shape and damageable parts, laser transmission line on atmospheric characteristics.

Adjust the mirror adaptive deformation parameters, tracking precision, aiming to provide parameters to the beam and fire control system; the last launch of high power green light laser, converge to the missile engine shell, a light time lasts about 3 ~ 5 s, the engine casing damage. In the whole process of operation, the control tower follow the ballistic missile servo.

The distant stars brighter, the green light laser can be regarded as the plane wave through the atmospheric turbulence, the wave front reaches the ground clutter. With adaptive optics telescope can be a part of such a distortion of light through the deformable mirror and the beam splitter into the wavefront sensor to detect the wavefront shape. Through the corresponding feedback algorithm promoting surface actuator array to adjust the mirror control, in a very short period of time will be reflected light is corrected for the closest to the plane wave form.

Of course, green light laser also has many limitations and difficulties, such as high speed regulation of large systems, such as air also has some dispersion, so different frequencies of light in the atmospheric disturbance will not the same, each job can only adapt to the relatively narrow band. If it is not very bright for the stars, but also to make an artificial laser guide star in the vicinity of the azimuth

Green light laser as a new type of photoelectric measurement equipment came into being, which provides a feasible solution for power line inspection

Green light laser is a cross regional project, from the power grid planning, surveying, design, construction, operation, management, maintenance, marketing, decision analysis and so on, have a strong demand for regional spatial information. LIDAR laser measurement technique with high precision, full three-dimensional characteristics, which is fine grid design and management, provides spatial data support scientific and efficient.

Green light laser is the most important part of the grid, and line corridor terrain, topography, surface features have great influence on the construction and safe operation of the line, is the area of concern for the circuit design and management. At present, the power line corridor space data acquisition are the main methods of artificial mapping, aerial survey and remote sensing. LIDAR laser measurement technology can be used for fast high precision 3D measurement of line corridor, so as to design, transmission line operation, maintenance, management of enterprises and professionals to provide faster and more efficient and scientific means.

Green light laser to obtain high precision 3D line corridor terrain, line facilities and equipment, and features of the precise three-dimensional information corridor, including the tower, hanging line position, wire sag, trees, buildings, and power line planning and design, to provide high precision measurement data of operation and maintenance.

Green light laser in the circuit design stage, need certain width in the range of measuring line corridor selected within the high precision, to optimize the path line and tower location, as well as reduce the construction investment. For the transmission line and the high-voltage power line using aerial photography in the construction design stage.

What happens when a person travels at the speed of light, while a green light laser in his hand is going forward? Will there be two times the speed of light?

This is actually the first conclusion, another theory. Originally thought that all human understanding of the universe, what research on decomposition rate of synthesis is very thorough. But suddenly one day, no matter what the launch on the platform of green light laser, measuring its speed is constant on another platform. And then you’re blind, melancholy, until the last one to help people find a new theory to explain this problem. So the answer is not because certain theory, light can travel faster than light, but so far, the experiment not even a little bit of super speed of light.green light laser1

“The relative velocity we assume that someone close to green light laser, then according to the theory of relativity, his time” relatively slow to close to us “(stop watch his speed, his aging speed, in our view, slow to almost stop); but in his opinion, his time is normal. That is to say, we are in two different time reference and him.green light laser2

Observation on the reference system in which we live, because of his green light laser time “relatively slow to close to us” stop – we can assume that the time to slow down N times. So in our view, this light is light from his relative speed c slow N times.green light laser3

Any of the two in the relative motion of the object, in fact, are in a different frame of reference, time lapse speed is different. Only our usual velocity relative to the green light laser is too small, so each time the different speed can almost be ignored.
