When light hits matter, several different reactions may occur. Light passes through the object, absorbed by it and some of it reflects back. The reflection is constructed of two governing phenomena - diffuse and specular light reflection. The difference between the two types depend on the surface light interacts with - diffuse is a mixture of rays scattered from an inhomogeneous, and specular from a flat homogenous surfaces. On top of that, light scattering from a live tissue, such as plant, returns with additional information. This is because plants absorb and reflect parts of the electromagnetic spectrum according to their need - absorbing the visual range for photosynthesis and reflects the near infra-red in order to avoid heat accumulation. This property makes reflectance spectroscopy a tool that can shed a light on internal chemical reactions within the plant. The main challenge is to focus only on the information that matters while cleaning out equipment distortions, environmental as well as meteorological effects and noise coming from the sample. To do that our group implements advanced statistical algorithms that enable the computer to identify and locate only the information that matters. Traditionally reflectance spectroscopy asks question related to the chemical nature of the plant - water content, lipids content, pigments contents etc. Out group asks a central question: is it possible to isolate physically reactions in these spectra? i.e. fluxes, chemical reactions which attenuate in time.
