Implementation of a Sample Turntable in Optical Scatter Measurement

摘要：

The concept and the measuring principle of BSDF (bidirectional scattered distribution function) are analyzed. According to the single reference standard measuring principle, a set of system based on personal computer for BSDF measurement is developed, which laser wavelengths range from visible to far infrared. Considering the error of the receiver view angle and the total scattering zenith angle, the uncertainty of this device is 0.75%. The experiments about the hemispherical reflectance measurements on the aluminium at θ1=30o,ψ1=30o and the granite at ψ1=0° were made when the incident angle is different, and the results shows that the effect of specular reflection is very obvious, the surface scattering is chief, and the whole surface tends to smoothly.
