Abstract
Methods and systems for ultrahigh-speed multi-parametric photoacoustic microscopy that include an optical-acoustic combiner (OAC) configured to reflect the laser pulses into the sample and to transmit the photoacoustic signals to the transducer are disclosed.
Claims9
A reflection-mode, ultra-high-speed, multi-parametric photoacoustic microscopy (PAM) system, comprising:
- a. a high-repetition-rate pulsed laser configured to produce laser pulses at first and second pulse wavelengths;
- b. a high-speed resonant galvanometer configured to scan the laser pulses in an optical scanning pattern;
- c. a cylindrically focused transducer configured to detect photoacoustic signals produced by a sample in response to the laser pulses;
- and
- d. an optical-acoustic combiner (OAC) configured to reflect the laser pulses into the sample and to transmit the photoacoustic signals to the transducer.
