Study on the variable angle hyperspectral imaging system with high precision boresight pointing

A variable angle hyperspectral imaging system with high precision boresight pointing was developed.High precision optical axis pointing and variable angle detection were realized by controlling the pointing mirror.The multi angle hyperspectral image with high precision pointing was obtained through a functional verification test.This imaging system has the advantages of simple optical-mechanical structure,small volume,light weight,real-time detection with variable angle and good adaptability on minitype unmanned aerial vehicle(UAV).These advantages promote the application of the multi angle hyperspectral remote sensing in forestry.
