the green laser beam light of green laser pointer

 Therefore, the infrared light band will has very little influence on the green laser beam light of green laser pointer .
The technology uses point measurement method for the measurement of steady flow, with good direction sensitivity, and can carry a three-dimensional measurement. NASA Lewis Research Center has been using the LDV dimensional measurement of the flow field in turbine components. The laser two-focus velocimetry. Oxygen and fuel combustion in the combustion chamber turbulence Games. Relative velocity of the fuel particles and air flow, fuel evaporation, combustion efficiency and combustion pollutants in the formation of an impact. Therefore, while the particle velocity distribution have an important role in the study of the combustion process. On the basis of laser velocimetry, W. D. Bachalo and Mike Houser of success to achieve the measurement of particle velocity. So that the infrared light band has little influence on the green laser beam light of green laser pointer .It will not interfere with a single absorption line, thus affecting the gas content measurement. The laser gas field analyzer is not to absorb the impact of watershed pollutants, dust, or window in the process gas, which is due to the calculation of the gas content is based on a unique single absorption line size and shape, and therefore a more reliable measurement, and reduce the need for maintenance. Because of its small but sturdy mechanical unit, the laser gas field analyzer is very easy to install. Consists of three basic units: transmitting and receiving unit directly assembled to the welded pipe or flue DN50/PN10 or PN16 Flange by itself flange can also be inserted between them with flange valve (recommended ball valve ).
Airborne scanning laser radar. Airborne laser radar referred to as LIDAR aircraft equipped with laser radar, digital cameras and positioning of the attitude determination device, to obtain the image-realistic high-precision digital surface model (DSM) and digital elevation model (DEM), a new mapping equipment. LIDAR system by scanning devices along the route collecting ground of the three-dimensional data by a specific equation solver into the appropriate value of the image, LIDAR data image is generated and the ground elevation model DEM. The system can automatically adjust the navigation width of an exact match it with the aerial width. Different field conditions, the plane accuracy of 0.15 to 1 m, height accuracy can reach 10 cm intervals of 2-12 m. It is to determine the power of green laser pointer timely and quickly.
