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.

Can you imagine now that science and technology have been able to put a few tens of kilograms of laser show into a piece of smaller than the cover of the chip and can do the same job?

What is laser show? Laser show is a micro machining technology using integrated circuit manufacturing and 3D silicon, the structure of micron and nanometer scale sensor, control processing circuit and even micro intelligent system interface, communication and power supply manufacturing in one or more blocks on the chip, it can be the ability to provide intelligent device to the external environment even the perception processing. The miniaturization, high efficiency, low cost of property, so that it can be applied to almost all products, has a revolutionary significance.laser-pointers1

Taking laser show as an example, equipment and sensor related costs, especially playing the self driving role of traditional mechanical eye, laser radar is located in the roof of the vehicle on the road occupied more than half of the manufacturing cost. At present, with the development of technology, even Google related equipment driving volume is much smaller, but the laser the roof of the radar still depends on the release of body design freedom appearance.

Laser show, have made progress in technology and application breakthrough. Since the equipment driving car is mechanical pulse laser transmitter, laser radar can completely replace the cumbersome equipment, with a coin size installed on the automobile bumper, the mechanical effect of laser radar is even better.laser-pointers3

Because in theory, as long as we can find enough representative laser show, you can use the statistical results of the probability of finding a mathematical model, and makes it very close to the real situation, so a lot of manpower cost savings or give users a more pleasant experience.

Under the irradiation of high powered laser, the optical image is formed by the imaging objective lens

High powered laser is converted into electronic signals by the image sensor. Then, the electrical signal is amplified by the image data processing system and synchronization control, sent to the image display, you can see the two-dimensional optical image of the object, so as to provide information for automatic driving vehicle driving environment accurately.

In the automotive field, the image sensor is mainly used in the high powered laser, such as reverse image, forward-looking, overlooking the panoramic parking car mirror image, replace, tachograph, forward collision warning, lane departure warning, detection of traffic signal recognition, pedestrian, adaptive cruise control, blind spot detection and night vision, to ensure that the weather in the visual system a variety of road conditions, can clearly identify the lane, the vehicle, obstacle, traffic signs and so on.high powered laser2

According to the different elements, the image sensor can be divided into CCD, CMOS and CIS three. High powered laser, CCD early, because of small size, high resolution, high sensitivity, high image quality, has been leading image sensor market. However, behind CCD, it also brings some problems, such as high cost. The resulting lower cost, lower power consumption of the CMOS sensor.high powered laser3

Compared with CCD, high powered laser has a simple way to read the information, output information rate, low power consumption, high integration, low price, after the launch soon by the many well-known manufacturers of all ages. And with the development of technology, CMOS continued to narrow the gap with CCD, now gradually developed into the core of the market.

Usually has dozens of layers of 2D images were superimposed per layer reconstruction, image acquisition and processing generally require several minutes or even tens of minutes, to quickly get the real-time three-dimensional image display and very difficult, with the principle of binocular vision and Bessel beam extended focal field as the foundation, proposed the strongest laser pointer three-dimensional scanning device consists of the four galvanometer, control of lateral position and inclination of Bessel beam includes three dimensions, break through the traditional laser scanning not only two degrees of freedom from the perspective of real-time switch restrictions.

 

Blue laser pointers is a new type of laser beam with non-uniform polarization and helical phase structure on the beam cross section

Blue laser pointers in laser processing, particle manipulation, it has very important applications in quantum information. Compared with vector beam or vortex beam, vector vortex beams in the interaction between light and matter has more degrees of freedom.laser1

The use of blue laser pointers, the polarization converter based on liquid crystal, laser resonator has been able to produce vector vortex beams. However, the beam generated by these methods are generally confined to the polarization state specific, and has a low threshold, low conversion efficiency and the large size and other shortcomings.

A vector vortex beam can be decomposed into a blue laser pointers,vector and blue vector polarization polarization with a dielectric film and Q vortex phase can be achieved through a spiral phase plate. The Q structure is integrated into the spiral phase plate, can be formed integrated device to generate vector vortex beam.laser3

Blue laser pointers is used to describe any vector vortex beams, the physical process can make the polarization and phase evolution has become more intuitive. Based on the theory of mixed order Poincare ball, arbitrary vector vortex beams can be decomposed into a vector beam and a vortex phase factor. The vector beam with a dielectric Q and vortex which factor can be achieved through a spiral phase plate. Through the control of polarization state of incident light, you can get mixed order Poincare ball on the corresponding point of the vector vortex beams.

In the laser pointers process, whether there will be a thermal effect, the thermal effect will have on the circuit board and components

We understand that has relied on machinery / plate cutting, manual cutting, PCB designers and manufacturers and other forms of traditional plate equipment is very worried about laser pointers will produce the bad processing. No wonder they will continue to focus on regional thermal effect of the laser, especially the influence on cutting in line in the vicinity of the components.laser pointers1

Especially for high risk near the cutting edge of the components are destroyed in the board process may be studied. In other words, the thermal effects of ultraviolet laser pointers line around to what extent, the thermal effect will damage the cutting line in the vicinity of the components?
