Abstract: The present invention relates to a stand-off optical measuring system based on Raman scattering for detecting and identifying chemical threat substances. The system comprises a spectrometer that comprises a dispersive device (104) in front of a 2-dimensional detector (105), the entrance of the spectrometer being a coded aperture (106-109). The measuring system is designed to be able to quickly adapt to different measuring conditions by the coded aperture being a programmable coded aperture.
