美国专利US6111640(2000年8月29日公布) 本发明提供一种用于对超光谱成像光谱仪进行定标的方法。首先,在光谱仪的视场中插入一块在相关光谱区反射比大致为100％的PTFE板(26),用石英卤钨灯照射该PTFE板,使来自该板的反射辐射充满光谱仪的视场,并用电子方法将光谱仪产生的图像记录下
US patent US6111640 (published August 29, 2000) The present invention provides a method for calibrating a hyperspectral imaging spectrometer. First, a PTFE plate (26) with a reflectance of approximately 100% in the relevant spectral region was inserted into the field of view of the spectrometer and the PTFE plate was irradiated with a quartz tungsten halogen lamp to fill the field of view of the spectrometer with the reflected radiation from the plate, The electronically generated image of the spectrometer is recorded
