media changes rapidly with depth. Using the theoretical investigatibris of:V, A. Ambtutsmnyan
(Izv. AN ArmSSR, No 1-2, 1944) as the starting point, the author investigates theoret*~ally
the spectral modification problem in detaAs. Graphs and tables present 1) the spectral con1po-

of P ; of the transmission coefficient, of the primary light transiniBsion coefficient, and of the
luminosity; and 2) the luminosity magnitude as function of depth for various values of the para-
meter j describing ratio of the flux -scattered forward (In the 21reolid anile) to the flku., scat-
tered backwards by a unit layer. The paper concludes by a brief discussion concernmig the:

ABSTRACT: The attenuation of a narre~w beam of light in a turbid medium consisting
of water in a tank, with optical deneity controlled by addition of milk or rosin,
I has been investigated. The absorptivity was varied by dissolving premeasured
vinounts of anilitic black. A narrow collimated beam at X = 5146 nm with a 3.4-cm2
cross section and a divergence of I' was 1)roduced by passing radiation from a
D!6h-250 lamp th-rough a mercilry filter. The results of the experiments were
surnarized in the form of graphs of the dependence of illumination on the optical
depth at different values of the extinction coefficientii (c) mid the dependence of
illumination on the sauare of the extinction coefficient aL dLfferent values of the
apticsl deoth (T). It was shown that as a result of the negligible contribution of
scattering, attenuation of light in slightly turbid media, in which c < 0.05 cni-1
and T is less than 10, obeys the exponential law of absorption (Bouguer-Lambert

law of absorpticn is not obeyed at tuKT depth, with the illumination at constant r
increasing with the increasing coefficient of absorption. As T was increased at

ABSTRACT: To check on a hypothesis that in a strongly turbid medium the orientation
of the intensity vector of the external radiation would be less important than in a
weak3.y turbid medium, and to obtain quantitative estimates of this difference, the
authors have experimented with the influence.,of the electric-intensity vector orients-
tion on the illumination produced by radiation in a light-scattering medium. The in-
vestigations were carried out with apparatus described earlier (Opt. i spektr. v. 18)
no. 4, 1965)z The polarization plane was rotated with the aid of a polaroid. The
theory of the experiment is briefly described. The tests were made with the optical
receiver immersed in the turbid medium to different depths. Plots are presented of
the percentage change of electric intensity against the orientation of the electric
vector and against the extinction coefficient. The results show that the larger the
extinction coefficient, the smaller the influence of the polarization angle on the

intensity. The plots of the change of intensity against the polarization angle
symmetrical about the value at 90% at which their relative change of intensity hat;
a maximum. It is concluded from the results that at large distances from the point
of penetration of the light into the medium, or in the case of strong turbidity., dif-
ferences in the orientation of the electric intensity vector of the incident radiation
do not change the illumi ion noticeably. However, when the turbidity is low and
the multiple scattering is small, the Mimi ion may change by a factor of two as
the angle of polarization changes from 0 to 90% This report was presented by AN BSSR

TITLE: Effect of the angular dispersion of a light beam on its penetration into a scattering
medium

ABSTRACT: The problem of the effect of the angular dispersion of a ligIA beam on illumination,
in a turbid medium was investigated experimentally. The experiments we re set up in a small
basin filled with turbid water. The method of investigation was such that it was possible to
change both the angular aperture of the radiator from 0.5 to 1800 at a constant luminous flux
entering the water ana the optical characteristics of the medium, the probability of photon
survival, and the optical depth. The cross sectional area of the light beam entering the water
2 a
was 3.14 cm . The authors examined the region of small optical depth %vhich corresponds to
a slightly turbid atancsphere, space, and water to shallow depths; the region of average optical

depths; and the region of large optical depths. It is concluded that die greater the probability
of photon survival, the slower the illumination decreases with an increase of the radiator
aperture angle. At large optical depths illumination depends on the angular dimensions of the
radiator but not as much as could be expected. Illumination drops not by several orders of
magnitude but only by a factor of 2-3 when an acutely directed radiator is replaced by a com-
pletely diffusive one. Orig. art. has: 4 figures and 2 formulas.

TITLE: Determination of the extinction coefficient of turbid media
SOURCE: AN SSSR. Izveatiya. Fizika atmosfery i okcana, v. 2, no. 7, 1966, 721-728
TOPIC TAGS: turbid medium, light scattering, light reflection coefficient
ABSTRACT: This article examines the problem of the effect of acattered light on the
effective magnitude of the- extinction coefficient as a function of the optical Para-
meters of the medium and angular characteristics of the source and receiver. TableB
of errors in the measured values of the extinction coefficient are presented and, by
using the data of these tables, it is possible to make recommendations concerning the
choice of the measurement instrument under certain conditions when a given accuracy
of measurement is required. Milk, an alcoholic solution of rosin, and a solution of
polystyrene in acetone diluted with distilled water were used as media having differ-
ent scattering indicatrices. Bouguer's law was used to determine the extinction co-
efficient. It was found that the error in determining the extinction coefficient forr
a milk medium was highest owing to the greater elongation of the indicatrix of refrac-
