Ranging equation formula. Monostatic and bistatic laser radar range equation, the general formula: where: laser power (W); distribution function for the beam; atmospheric transmittance for the transmitter to the target; transmitter optical system efficiency; φ is beam width or divergence (rad); transmitter to target distance (m); target laser cross section (m2); atmospheric transmittance for the target to the receiver; target to receiver distance (m); D, for the receive window diameter (m); receiver optical efficiency of the system; received power (W). The development of microwave radar, laser radar is the same location principle. The difference is that the microwave wavelength and beam width is much larger than the laser targeting error is very small; laser radar is the opposite.
Mode consists of three main software settings to manipulate the measuring instruments. Parts detection method that system measurements followed by the feeding system of discrete parts. The roller or belt conveyor detection of a large continuous surface measurement operation. Laboratory tests for the materials part manually by an operator. Users select the adjustment of the corresponding software model and measurement instrument itself. Lasercheck measurement surface, the surface must be clean. The optical Dimensins developed a cleaning device to cope with the application of the measuring instruments. Lasercheck measurement of the data may indicate changes like the grinding process. This data reflects the change in the wheel when the wheel load, and reflects the impact of the process of grinding wheel dressing.
Lidar System Data Division, Lee would like Lidar (Light Detecting And Ranging) technology is a beam to detect objects and determination of the distance from the high-tech integrated systems represent the forefront of digital mapping technology. Airborne GPS provides the spatial location of the Lidar systems, inertial measurement system to provide the direction of the Lidar laser, laser system provides laser pulses, the computer system to provide high-speed, large-scale data storage space and processing power. In recent years, scholars of the application have done a lot of the lidar. The research focused on the correction of the lidar data and matching close small power lidar range finder target-based surface reconstruction. It is the revised and improved design of the dust-proof switch of green laser pointer .
And housing modeling studies based on orthophotos or remote sensing images. Lidar technology background Laser 1960s, developed a new discipline. 40 years, after the basic theory and applied technology research, has entered the all-round development and application stage. The development and application of laser technology not only makes the old optical technology to break new ground, and extensive penetration into the various disciplines. It has become a powerful research tool in the field of science and technology, and effective means to stimulate and promote the development of science and technology. The use of laser remote sensing equipment, can be traced back 30 years ago. The period from the 1960s to the 1970s. The design makes green laser pointer much easier and more convenient.The quality control of green laser pointer is always the important process
