Research on Laser Atmospheric Transmittance on the Sea

The measurement of fluid velocity by laser Doppler Effect is the trend of the velocity measurement filed in recent years, the laser Doppler velocity measurement has the characteristics of high accuracy and non-contact, but due to the laser's restrict, ...

To measure the surface texture study on the aggregate, this paper based on the principle of laser light scattering method, using the PSD texture analysis, and adopt the existing laser equipment cross-section for the texture sensor, which issued by the ...

For the sake of developing an ice shape profilometer in icing wind tunnel, the technique of ice shape measurement based on laser sheet and machine vision is studied. The measurement principle and computing theory have been demonstrated in detail. The ...
