Internal project (CIR)
An in-house project to measure the spectral distribution of organic samples at the micrometric scale.
Our objective: To design and develop a hyperspectral microscope in the visible and near infrared. Biological cells from plants and algae were analysed with a spatial resolution of 9 µm and a spectral resolution of 2.1 nm. Nitrogen levels, indirectly linked to spectral information, were mapped. Inorganic samples, including minerals and metals, were also observed to analyse their chemical compounds. This work has been submitted to Applied Physics Letters.
