Determination of the optical parameters of tissues is a necessary element of laser medical diagnostics and therapy planning. In this work a mathematical model of the photon migration in tissues is considered in the assumption of the harmonic modulation of the incident laser light. The scattering coefficient and the photon's life time in virtually absorbed state can be calculated from the modulation coefficient and phase shift between incident and scattered light. Frequency-domain measurements were performed using two laser diodes (wavelengths 805 and 850 nm) as light-modulated sources and fiber-optic light guides for delivering the light to tissues surface and collecting the back scattering output. It is shown that measured difference in phase shift of scattered light intensity is proportional to difference in mean pathlength of photons at two wavelengths.

In the present paper a brief overview of the developed methods of blood microcirculation analysis in vivo is given. The theoretical investigations into the processes of focused Gaussian beams diffraction in blood capillaries with a diameter a bit greater than the erythrocyte size have been carried out. Also, the diffraction of focused Gaussian beams in the flows of dissolved blood and its separated components in glass capillaries has been experimentally studied. The range of validity of the measurement method of the blood flow velocity in narrow blood capillaries, using focused Gaussian beams diffraction, has been analyzed.

The main principles of flow cytometry and spheres of its application are given. The features and metrological characteristics of the flow counter-analyzer with laser beam space scanning suggested is considered. The experimental results with latex particles and biological cells (red blood cells and its complexes) are presented. It is shown that the laser beam scanning in flow hemacytometry may be useful not only to solve the blood formula problem but for designing the devices which may give an opportunity to investigate the aggregates of blood cells.

One of the important methods for the biomedical objects structure investigations is the statistical analysis of the partially developed speckle patterns formed in the output plane of the coherent scanning microscope (CSM). By means of CSM the speckle intensity's statistical properties for the samples of the human epidermis strippings have been investigated. The strippings under testing were considered as random phase screens with an unknown correlation length and phase deviation; for such objects the computer simulation of the laser light diffraction has been carried out.

A preliminary study into the spatial resolution that may be achieved for time resolved near infrared imaging through highly scattering media has been performed. The spatial resolution, for time gated images, has been investigated quantitatively by measuring the edge-spread function for scattering media of different properties and at different depths. Transmission scans of two absorbing rods, spaced by different distances, were used to qualitatively study the contrast obtained at different integration periods or using the measured mean time-of-flight. Both spatial resolution and contrast are improved as the time gating interval is reduced. However, for thick tissue sections it may not be possible to reduce the spatial resolution below about 10 mm, because of the small amount of light arriving at these early times.

The paper investigates the imaging response of cw coherent systems for imaging through scattering media. Particular attention is paid to the confocal optical technique, and experimental results are presented that show the effect on the imaging spatial resolution as the optical configuration is altered. It is seen that if the scattering concentration is increased, there is a sudden reduction in spatial resolution. This point defines a so called transition region. We show how this transition region can be moved by altering the optical configuration. We also see that when heavily scattering media is being examined, it is possible to vary the optical configuration, what is in effect changing the optical response to various scattered components of light. This procedure can be likened to adjusting the time window in the pulsed time of flight technique, and is further investigated in the companion paper.

Several approaches to increasing the number of parameters of suspended particles that can be determined by a spectroturbidimetric method have been analyzed. It has been shown that, in principle, this problem can be solved invoking spectral characteristics obtained under conditions of complete or partial particle orientation in the stationary and relaxation regimes. Informative potentialities of combining the methods of electro-optics and spectroturbidimetry have been considered. It has been found that eventually for a given disperse system in situ, it is possible to obtain the following set of parameters: particle mean size, shape characteristic and refractive index, number and mass-volume concentration of particles, their total surface area per unit volume of the suspension and the effective value of particle surface polarizability.

quantification and localization using diffuse photons in a highly scattering medium 1993

作者： Kang, Kyung A. Chance, Britton Johnson Research Foundation Department of Biochemistry and Biophysics University of Pennsylvania PhiladelphiaPA19104 United States

In this paper, phase and intensity information is predicted for a system consisting of two absorbers immersed in a highly scattering medium and two light sources (in- and anti-phased) with a single detector. Phase and intensity information in this 3-D system with absorbing boundaries is obtained by solving the photon diffusion equation by B-W-K technique, with proper boundary conditions. The capability of phased array to resolve two absorbers with a single detector is correlated with a geometric relationship among sources, a detector, and absorbers.

Laser Doppler flowmetry has widely been used to investigate the real time changes of the local blood flow in the inner ear. However the optical properties of the cochlea have not thoroughly been investigated. We have investigated the optical characteristics of the bony layer of the guinea pig cochlea by means of an integrating sphere and determined the absorption and scattering coefficients. A Delrin plate with approximately the same optical properties as the bony layer was used as a model in some of the measurements. In a flow model the geometrical conditions of the cochlea were studied. The flow model consists of a single capillary and the Doppler shifted signals were measured by a single optical fiber. Results show, the changes of the Doppler shifted signals were related to the distance between the photodetector and the scattering medium. From our results we can conclude that the laser Doppler measurements include information on the blood flow in structures deeper than 1 mm below the bone surface (guinea pigs).
