摘要： A photoacoustic catheter includes an elongated catheter body and a housing positioned near a distal end of the elongated catheter body. A length of multimode fiber extends through the elongated catheter body and has a distal end that is beveled at about 45° relative to a longitudinal axis of the multimode fiber and is positioned in the housing. An ultrasonic transducer, electrically connected to an electrical wire extending along the elongated catheter body, is positioned within the housing. A mirror element is also positioned within the housing and includes a mirror surface beveled at about 45° relative to the longitudinal axis of the multimode fiber. The catheter is operable to deliver an optical wave through the multimode fiber and to deliver an ultrasonic wave collinearly from the housing and out of an aperture of the housing to obtain optical data and ultrasonic data within a mammalian luminal organ.

摘要： A microsecond-scale stimulated Raman spectroscopic imaging system having a light source, such as a laser output that provides two femtosecond laser beams and a modulator to modulate the laser intensity at frequency between about 1 and about 100 megahertz. The system can further include a medium that chirps the two femtosecond beams to generate a spectral focus in a specimen, and a galvo mirror or resonant mirror pair to scan the two femtosecond beams in two dimension on the specimen. An objective lens can focus the two laser beams into a specimen or sample and a resonant delay scanner configured to produce an optical delay to the pair of chirped beams in said specimen and a tuned amplifier or lock-in amplifier can be used to extract the stimulated Raman-signal shift at the aforementioned modulation frequency.
