In fact, there is a laser pointer pen ranging method is phase method, phase measurement method can not be too far, but the precision is much higher

The phase method is to put one or more low frequency (relative to the light frequency modulation) in laser pointer pen, similar to the modulated audio signal in radio RF signal. The specific approach is: Using low frequency signal to control the output power of the laser, the laser reflection signal received power will change with the low frequency signal. Phase of the received signal and the output signal will be compared.

Due to the use of phase ranging laser pointer pen is a continuous output, the peak power is smaller, so the maximum distance is much smaller than the pulse method, usually non cooperative target maximum range of only a few kilometers, want to measure the distance to the moon is not possible.laser pointer pen3

Let laser pointer pen and photosensitive optical beam from a certain distance, so the measured points and lines that reflected light photosensitive unit and laser beam path will form an angle. This angle is measured, then according to the triangle of knowledge, we can calculate the measured point to photosensitive unit distance.laser pointer pen1

This is not the same light is relatively long, the laser pointer pen according to the sine wave modulation. The sine wave travels at the speed of light, the first 0 degrees behind some distance. What is the light emitted by the reflected light to the degree of the difference is the phase difference, on behalf of the distance (2 times).

In addition to the laboratory fire, electricity, the other thing is to prevent laser pointer pen damage

Laser pointer pen is greater than 500MW, the laser belongs to the class classIV laser, is the highest level of GB in the laser beam, not only itself to the eyes, skin and other electronic optical equipment, causing burns, and scattered light, reflected light can be dangerous, and has extremely high fire risk, and I to experience you, my right eye retina by green laser burns, 200mw532nm is not reversible, so now there will still be floaters in the operation of the laser, including other equipment must be Caution! Problem!laser pointer pen1

In addition to the lab fire, electricity, another thing is to prevent laser pointer pen damage. The laser beam is not directly required to do experiments by laser laser, although only 4mW, this is not a joke. The simplest is to increase energy to increase the voltage, then brush the erupt laser burned. This kind of thing, only to see to know into the eyes, is already late into the eyes.laser pointer pen2

Do you like to laser pointer pen might not know, more than 3b of the laser scattering light to the human eye may harm the.3b is 5 to 500 or 1 MW to 500 mW laser eyes can’t remember. I usually use power meter measuring 20 MW at that scattering light spot stand. Don’t you how to play at home, be sure to wear goggles and letting people know what you are doing.laser pointer pen3

The first time I know that laser pointer pen can also lead to blindness. It can remind the laser technology to play house. And laser eye damage is irreversible, will leave a permanent blind spot. However, the brain will “play” on the spot, let you not aware that, like the human natural existence of blind spots. But this does not mean that good for your eyes.


With a large number of laser pointer pen from different angles at the same time to illuminate the tiny mirror, the mirror can still reflect the light of each laser pen?

Because of a beam of light is independent of each other, so in principle there should be no problem, the light can be normal reflection. But a closer look, the problem is there is a “great number”, which involved two questions: first, what are the effects of laser pointer pen; second, the effect will be the impact of the situation for the reflection.laser pointer pen1

Laser pointer pen radiation pressure produced in two ways: one is the pressure formed by the radiation pressure of the laser, called a pressure. The radiation pressure of the laser was weak, but the energy is concentrated, the pressure is considerable. After another laser tissue, can be secondary two times the pressure, this is due to the strong laser in biological tissue, in addition to outside pressure, and steam vaporization pressure, anti shock, thermal expansion, ultrasonic pressure and electrostrictive pressure caused by many factors.

Controlled by the software of laser pointer pen system, the laser beam setting is controlled by ablation, which can be cut on a certain material according to the required depth

Laser pointer pen red laser has other benefits that are not available, which can limit the thermal stress. This is because most of the laser pen light system running in low power state. By using is sometimes referred to as the “process of cold ablation, beam diode laser will produce a narrow heat affected zone can be. Burring, effect of carbonization and other thermal stress to a minimum, and the use of high power most powerful laser usually have these negative effects. laser pointer pen2

Laser beams wavelength is smaller than the wavelength of light, the eye is not visible. Although you can’t see the military laser, but these laser pointer pen is able to make short circuit characteristics more accurately focus, so as to produce extremely fine and retain the excellent positioning accuracy.laser pointer pen3

Laser pen light is applied to the resin and copper showed high absorption rate, in the processing of glass has a proper absorption rate. Only the comprehensive absorption rate of expensive diode laser will be better in these materials processing. The main difference of this material makes most powerful laser become the best choice for the application of laser beams a lot of  in the industrial field, wiring circuit production from the basic military laser, to produce compact embedded chips and other senior technology are common.

Diode laser between  most powerful laser  and the needs of a wide range of laser beams hindered the further investment of small and medium-sized enterprises and create a reliable military laser ability, because the potential rate of return on investment is too low. Taking into account of all these factors, and public policy related to digital pay special attention to laser pointer pen, because they are the backbone of red laser manufacturing.

The advantage of laser pointer pen radar is very obvious, its detection range is wider, and the precision is higher

Target detection using laser pointer pen, to obtain data and generate accurate digital elevation model. Its working principle is not difficult to understand, is to transmit and receive red laser. in laser pen light, each component contains a transmitting unit and a receiving unit. The transmitting / receiving component and a rotating mirror with together, can scan at least one diode laser.

Send not only most powerful laser reflection mirror diode laser, but also can make the reflected laser beams then reflected to the receiver. By rotating mirror, can achieve 90 to 180 degree angle, and greatly reduce the complexity of the design and manufacturing system, because the military laser is the only movement mechanism.

The detection distance is the principle of light return time based on laser pointer pen red laser by pulsed light, exposure to the target after a portion of the reflected light back, install a laser pen light diode in nearby, it can detect the signal back, by calculating the emission and detection of the time difference can be calculated on the target the distance of.Diode laser once activated can collect a lot of most powerful laser.

But laser beams in extreme weather or the performance of smoke environment is greatly reduced, and because of the large amount of data collection, the price is very expensive. Red laser radar currently installed in military laser and laser pointer pen (unmanned vehicle on the line number, the better the performance, cost more expensive), welcome to come.

Algae have a powerful light harvesting system – proteins that absorb laser pointer pen and then convert into energy

Cryptophyte algae usually live in other organisms absorb most of red laser below. Accordingly, these algae evolved to rely on people who are not captured by their neighbor’s laser pointer pen laser pen light is mainly to thrive. These algae collected the diode laser energy, and pass it to a convert to most powerful laser molecular network, in which the chlorophyll molecules need to perform important photosynthetic chemistry.laser pointer pen1

Laser beams through the system speed is impressive, and to study their prediction of military laser.Red laser is always confused than the observed slow speed three times. “These energies through the protein time scale — we will never understand why this process can be so fast,” says pen pointer laser author.laser pointer pen2

By using a complex diode laser method, researchers can measure the molecular most powerful laser, and the tracking system in the energy flow fundamentally. Under normal circumstances, the absorption signal will overlap, so that they could not be assigned to protein complexes in the laser beams, but the team through the protein to cooling very low temperature can improve the signal military laser.
