Abstract

Coefficients of light absorption μ_a and scattering μ_s for biological tissues lie within a broad range - minimum ones for healthy eye tissues up to higher values (f.e. μ_a = 0.3 cm^-1 and μ_s = 40 cm^-1 at 633 nm for muscle tissues) for other and mainly turbid tissues. The specific feature of the transparent PLZT ceramics (having absorption μ_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 (Pb_0.91La_0.09Zr_0.65Ti_0.35O₃). 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.
