Multi-scan optical system

A multi-scan optical system comprising:

• an excitation source configured to emit composite light;
• a hydra fiber cable disposed downstream of said excitation source, said hydra fiber cable having a head and a plurality of tentacles configured on the ends of said hydra fiber cable respectively, wherein:
• said head is configured to collect the composite light emitted by said excitation source via a second lens;
• and
• said plurality of tentacles is configured to multiplex the composite light collected by said head, and further configured to transmit multiple composite lights;
• a wavelength selector having a plurality of optical slits (s1-s8), said wavelength selector configured to selectively collect and filter the composite light directed by a first lens and the multiple composite lights transmitted by said plurality of tentacles, and further configured to direct a plurality of spectral line scans, of different wavelengths, corresponding to each of said plurality of slits (s1-s8);
• and
• a detector configured to detect said plurality of spectral line scans reflected by an optical element for spectrometric analysis.
