Paper Abstract

Coefficients of light absorption (mu) a and scattering (mu) s for biological tissues lie within a broad range. Minimum ones foe healthy eye tissues up to higher values (f.e.(mu) aequals 0.3 cm -1 and (mu) s equals 40 cm 1 at 633 nm for muscle tissues $1)) for other and mainly turbid tissues. The specific feature of the transparent PLZT ceramics (having absorption (mu) a>0.1 cm -1 in the visible and in the near infrared spectrum range) is electrically controlled light scattering. The present work reports on experimental results of the light transport and backscattering for PLZT 9/65/35 (Pb0.91La0.09Zr0.65Ti0.3503). We propose PLZT ceramics with fast and continuously controllable light scattering as an optical phantom for photon migration studies and for scattering obstacles in vision disability tests.
