Absorption spectra of four tissue components and the schematic of NIR-OR-PAM. (a) Absorption spectra of oxyhemoglobin (HbO2) (150 g/L or 2.3 mM in blood), deoxyhemoglobin (HbR) (150 g/L or 2.3 mM in blood), water (80% by volume in tissue), and lipid (20% by volume in tissue) from 250 nm to 1150 nm. (b) Schematic of the NIR-OR-PAM system. ConL, condenser lens; CorL, correction lens; DC, dye cell; DM, dichroic mirror; FM, flip mirror; M1, M2, and M3, mirrors; ND, neutral density filter; OL, objective lens; PH, pinhole; PL, pump laser; RAP, right-angle prism; RhP, rhomboid prism; SHG, second harmonic generator; SOL, silicone oil layer; UT, ultrasonic transducer; WT, water tank.
