The optoacoustic method of monitoring absorbed optical energy distribution in tissues was employed to measure changes in glucose concentration in vivo. Glucose osmotic and hydrophilic properties cause reduction of tissue scattering as a result of glucose concentration increase around scattering particles and fibers. The opto-acoustic (OA) method utilizes time-resolved measurements of laser- induced ultrasonic profile in tissue resembling the distribution of absorbed optical energy. This opto-acoustic profile yields effective optical attenuation coefficient, which decreases with decrease of scattering. Glucose effect has been investigated initially in phantoms resembling optical properties of sclera and polystyrene microspheres water solution colored with potassium chromate and then in sclera in vitro and in sclera of live rabbits. The forward mode of opto-acoustic detection was used in the experiments in vitro. Experiments were performed in UV spectral range at the wavelength of (lambda) equals 355-nm. Experimental results demonstrated that an increase in glucose concentration from 5 mM to 60 mM was expressed in the 3 percent reduction of (mu) _eff in aqueous solution of polystyrene microspheres. The effect of glucose on sclera in vitro was more prominent and measured as 10 percent reduction of (mu) _eff with increase of glucose concentration from 1 mM to 50 mM. It was found that both the amplitude and the profile of OA signal were influenced by mechanical pressure applied to sclera specimen toward the surface of OA transducer. In experiments in live tissue, the backward detection mode was employed, as the only one side access to the tissue surface was available. In experiments in vivo the opto-acoustic profiles were measured in rabbit's sclera before and after intravenous glucose administering. The glucose concentration in rabbit blood was simultaneously measured using commercial device employing chemical analysis of blood. Experimental results demonstrated that a 1 mM increase in glucose concentration resulted in a 3 percent decrease of optical attenuation in rabbit sclera in vivo. Such a pronounced change of optical scattering in sclera in response to physiologic change in blood glucose concentration encourages us to continue measurements in vivo and modeling glucose effect on tissue optics.

A laser optoacoustic sensor (LOAS) for the nondestructive characterization of layered structures of composite materials is presented. The method employs laser pulses for the generation of wide-band acoustic transients in the ultrasonic frequency range from 100 kHz to 10 MHz. The acoustic transient signal is generated at the very surface of materials under testing. The laser wavelength is chosen to achieve the desirable optical attenuation in the material and, thus, to induce acoustic transients within desirable frequency range. The detection of laser-induced ultrasonic signal, its temporal profile and the ultrasonic spectrum, may be performed either in transmission mode or in reflection mode. The laser optoacoustic sensing in transmission mode (LOAS-T) is performed at the surface opposite to the irradiated surface. LOAS-T utilizes measurements of acoustic attenuation coefficient as a function of ultrasonic frequency within the range of laser-induced frequencies. The laser optoacoustic sensing in reflection mode (LOAS-R) permits measurements of ultrasonic transients scattered from the volume of the material under testing. The ultrasonic signal is detected at the site of laser irradiation. The measurements of the reflected ultrasonic signal is frequently the only mode available for the nondestructive evaluation, because usually only one side of the evaluated object is accessible. Samples of layered graphite-epoxy composite materials with volume percentage of micropores from 0 to 1.2% were studied with LOAS. In the ultrasonic frequency range from 1 to 5 MHz, the acoustic attenuation coefficient was found to increase with an increase of relative volume of micropores. The 'noise' component of the scattered acoustic pulse sharply increases with the increase of relative volume of micropores. A 1% increase in the relative volume of micro-pores results in a 3 times greater 'noise' component in the laser optoacoustic signal. Results indicate possibility for the LOAS to be utilized as a diagnostic system for the quantitative characterization of composite materials.
