Discrete models of reflection, absorption, and scattering of laser light through biological materials

摘要

This paper contains a description of discrete models of reflection (DiMoReLL), discrete models of absorption (DiMaLL), and models of scattering (DiMoScaLL) of laser light by biological materials. Individual models are integrated into a complex model-DiMoRAS. All the models are realized by finite automata (cellular automata, homogeneous structures). Finite automata comply with basic three-dimensional (cubic) elements of bounded area of biological material. Each of the three-dimensional elements is defined by three integer coordinates (i, j, k). For each of the elements (i, j, k), a status vector D-i,D-j,D-k = D(i, j, k) is defined in discrete time t. Status vector D-i,D-j,D-k contains four basic components that are generally vectorial elements of three-dimensional matrices defining the intensity of laser light (matrix I) and standardized values of reflection (matrix R), absorption (matrix P and matrix A), and scattering (matrix S) of laser light in individual three-dimensional elements. Spot functional models of reflection, absorption, and scattering of laser light whose characteristics comply with concrete biological materials are used to define the corresponding values. Transition rules of the status vector are expressed using Boolean functions. [References: 9]
