用于农田土壤监测的高光谱成像仪
Hyperspectral Imager for Farmland Soil Monitoring
摘要
Abstract
Soil spectral analysis technology has features of fast analysis speed,low cost,no risk,no damage,and it can inverse a variety of ingredients at the same time.Based on hyper-spectral imaging technology,we can quickly obtain soil properties and its spatial distribution characteristics.In this paper,we design a UAV hyper-spectral imager based on the demand of farmland soil monitoring.The Offner convex grating spectral imaging system was selected to achieve non-spectral line bending and colorless distortion design results.The diffraction efficiency is 15% ~ 30% in the range of 400 ~ 1 000 nm wavelength.The ground imaging results are clear,it can obtain hyper-spectral images of ground target of covering a width of 0.6 km and ground resolution of 0.6 m at 3 km altitude.It provides 120 spectral bands of hyper-spectral images at the wavelength range of 0.4 ~ 1.0μm.The spectral data are accurate and stable.The results show that this hyper-spectral imager meets the design requirements and can quickly obtain the high-precision imaging spectra of the agricultural soils,thus achieving the monitoring of farmland soil.关键词
