A piezoelectric photoacoustic spectroscopy (PZT-PAS) system was developed for non-invasive measurement of biological tissue. It detects a single frequency of ultrasound induced by pulse-modulated mid-infrared laser light. PA spectra of optical phantom and biological samples were obtained, and the relationship between PA signal intensity and optical absorbance in the fingerprint region was analyzed to estimate the optical absorbance. The resonance vibration of induced ultrasound was utilized to increase the signal strength for biological tissue measurement. Consequently, a PA spectrum reflecting the absorption of components in biological tissues was obtained.
For the non-invasive measurement of biological tissue, a piezoelectric photoacoustic spectroscopy (PZT-PAS) system that detects a single frequency of ultrasound induced by the irradiation of pulse-modulated mid-infrared laser light was developed. PA spectra of the optical phantom and biological samples were obtained, and the relationship between the PA signal intensity and optical absorbance in the fingerprint region (930-1,200 cm(-1)) was analyzed to estimate the optical absorbance. The resonance vibration of the induced ultrasound was utilized to further increase the signal strength for biological tissue measurement. Consequently, PA spectrum reflecting the absorption of components in biological tissues was obtained.
