Fibre Optic Reflectance Spectroscopy (FORS)
FORS is a portable and flexible system for in situ reflectance spectroscopic measurements that complements visible/near infrared spectral imaging by providing higher spectral resolution and simultaneous capture of a wide wavelength range. The ISAAC mobile lab is equipped with a range of portable and flexible FORS systems for both close range and remote measurements.
