Thin optical phantom for mimicking human body and method of manufacturing the same

摘要

The present invention relates to a thin film optical element having a thin film thickness and a uniform surface property in a micrometer range using a spin coating method and having various optical properties such as absorption and scattering such as tissues, Phantom, and a manufacturing method and apparatus thereof.To this end, the present invention relates to a method for preparing a composite material having a non-Newtonian fluid property to simulate optical characteristics similar to human skin tissue by mixing a subject and a hardener in a ratio of 2: 1, A light medium composed of any one of an absorbing material that absorbs light of a predetermined wavelength range so as to be able to emit light of a predetermined wavelength range or a scattering material that scatters light of a wavelength range selected to emulate optical scattering characteristics of a human body, Forming a mixed solution on the mixed material to form a mixed solution, setting a spin speed, a number of rotations, and a rotation time of the spin coater, and forming a coated surface by spin coating using the mixed solution as a spin coater solution And a thin film optical phantom by the method of manufacturing the thin phantom phantom, It allows the use of the thickness-specific analysis of the optical properties and structural characteristics of the tissue.;
