green laser pointer can be adjusted to burn the match
Compared with the general optical ranging technology, it has the advantages of convenient operation, simple system, and day and night work. Compared with the radar ranging, laser ranging has a good anti-jamming and high precision. Space in duplicate ranging at the same time, a thin laser beam scanning, and target distance, angle and speed of information, which is the laser radar. The lidar can achieve many of the traditional Lei Dada less than the performance requirements. Divergence angle of the laser energy is concentrated. Able to achieve extremely high detection sensitivity and resolution; its extremely short wavelength makes the size of the antenna and the system can be very small, these are the traditional radar incomparable. Compared with microwave radar, laser range finder directional, small size and light weight. green laser pointer are sold in the current market.
Ideally suited for carrying space in a spacecraft target distance measurement. The laser ranging technology combines laser technology, and photon detection technology, signal processing technology, a number of technical Ranging accuracy is high. Large measurement range, high reliability, to meet the space the target precision, the odometry ranging requirements. Has been applied widely in the field of space measurement. Background and significance. Laser is a nature did not exist, due to the shock issue with good directionality and high brightness, good color and good coherence properties of light, the laser characteristics: directionality - of ordinary light ( The sun, incandescent or fluorescent) light, in all directions and the direction of the laser light can be limited to less than the solid angle of several milliradians. The user speaks highly of green laser pointer .
This allows the illumination in the direction of irradiation to raise a million times. Laser collimation, orientation and distance measurement is to use a good direction this feature. - Laser brightness of the brightest light source, only the hydrogen bomb explosion instantly intense flash can be comparable to it. Sunlight brightness is about 103 W / (cm 2 ? steradian), a high-power laser output brightness of the sun from 7 to 14 orders of magnitude higher. Thus, although the total energy of the laser are not necessarily great, but since the energy is highly concentrated, it is easy to generate high pressure and tens of thousands of degrees Celsius or even millions of degrees Celsius in a tiny point. Laser drilling, cutting, welding and laser surgery is to use this feature. No matter how large the power of green laser pointer is.
