Snapshot multi-spectral-line imaging for applications in dermatology and forensics

摘要

Performance of multi-spectral imaging critically depends on image acquisition time and working spectral bandwidths.Ultimate performance can be achieved if a set of monochromatic (single-wavelength) spectral images is obtained by asingle snapshot - a technique provisionally called "snapshot multi-spectral-line imaging" or SMSLI. The SMSLIprinciple and the developed prototype devices for 3, 4 and 5 spectral line snapshot imaging are described. Two potentialpractical applications of SMSLI are discussed – for fast mapping of the main in-vivo skin chromophores and fordetection of counterfeit banknotes and documents.
