DETECTION SYSTEMS AND METHODS USING COHERENT ANTI-STOKES RAMAN SPECTROSCOPY

摘要

Systems and methods for remote and/or portable detection are provided. The system can include a source (305) of coherent laser pulses, components (315,320) for converting the coherent laser pulses into first beam pulses (391) at a first wavelength value, second beam pulses (392) at a second wavelength value, and third beam pulses (393) at a third wavelength value. Systems can further include optical components (330) configured to delay at least one of the first beam pulses, the second beam pulses, and the third beam pulses in order to create delayed beam pulses, and a focusing component (340) configured direct a substantially collinear combination of the delayed beam pulses and two of a set of: the first beam pulses, the second beam pulses, and the third beam pulses, onto a sample (355).
