摘要：

UV Raman hyperspectral datacubes were acquired by filtered imaging of a laser illuminated scene. The laser excitation wavelength was scanned over the Stokes Raman band relative to fixed narrow bandpass optical filters. Two different 0.3 nm wide bandpass filters with center wavelengths 248.4 and 264.1 nm were used and the excitation wavelength was scanned in steps of 0.2 nm. Results are presented for persistent chemical warfare agents and simulant chemicals on different surfaces.
