Multi-angle spectral data acquisition system can measure the bidirectional reflectance characteristics of vegetation and crops. With the high spectral resolution images from remote sensing satellites,the parameter information of vegetation structure can be obtained. The multi-angle spectral data acquisition system includes mechanical system and control system. Mechanical system is consisted of zenith institution and azimuth institution. The diameter of azimuth circle orbit is 4 meters while the radius of guide rail for zenith circle is 1 meter. The acquisition system is characterized by simple structure, easy installation and transportation. Furthermore, there is no shade in the spectrometer′s view. Control system provides a variety of measurement modes to meet the needs of different observations. The observation parameters can be entered into control platform so that it can be easily alteres and operated.
