subject

description

ABSTRACT Coefficients of light absorption ta and scattering for biological tissues lie within a broad range - minimum ones forhealthy eye tissues up to higher values (fe. t a 0.3 cm and i = 40 cm' at 633 nm for muscle tissues ) for other andmainly turbid tissues. The specific feature of the transparent PLZT ceramics (having absorption t a > 0. 1 cm in the visible and in the near infrared spectrum range) is electrically controlled light scattering. The present work reports onexperimental results of the light transport and backscattering for PLZT 9/65/35 (Pb091La009Zr065Ti035O3). We proposePLZT ceramics with fast and continuously controllable light scattering as an optical phantom for photon migration studiesand for scattering obstacles in vision disability tests.Keywords: light propagation in biological tissues, controllable light scattering, optical phantom, PLZT ceramics. 1. INTRODUCTION A number of optical phantom for simulating of light propagation in turbid biological tissues using silicon dioxide,mtralipid, polystyrene particle composition in water and agarose is quoted in literature 24•
