VNIR
(Redirected fromVisible and near-infrared)
Thevisible and near-infrared(VNIR) portion of theelectromagnetic spectrumhaswavelengthsbetween approximately 400 and 1100nanometers(nm).[1]It combines the fullvisible spectrumwith an adjacent portion of theinfraredspectrumup to thewater absorptionband between 1400 and 1500 nm. Some definitions also include the short-wavelength infrared band from 1400 nm up to the water absorption band at 2500 nm.[2] VNIRmulti-spectral imagecameras have wide applications inremote sensingandimaging spectroscopy.[3]Hyperspectral Imaging Satellitecarried twopayloads,among which one was working on the spectral range of VNIR.[4]
