Optical system for detecting turbidity medium and biological tissue optical parameter and detecting method

Abstract

Disclosed are an optical fiber system and a measuring method for measuring a turbid medium and a biological tissue optical parameter, comprising light source inputting, optical fiber measuring, controlling, data processing and calculating. The light source inputting is connected with the optical fiber measuring which is connected with controlling, data processing and calculating which are connected with the light source, and the optical fiber measuring is connected with the turbid medium or biological issue. The method is that real-time spectrum signals output by a measuring apparatus stores optical signals with various wavelengths according to the wavelengths; in a light transfer theoretical calculation sub-procedure, the stored real-time optical signals with various wavelengths are demodulated by mathematic treatment and then the actual measured optical signals are calculated; the actual measured optical signals are compared with the calculated optical signals, and then the optical parameter of the measured sample is adjusted to make the differences between the calculated optical signals and the actual measured optical signals less than the preset value, the optical parameter of the measured sample is output finally. The measuring system of the invention is simple and can accurately measure the optical parameter of an original body or living body in no need of leaving the living body sample.

Description

technical field [0001] The invention relates to an optical fiber detection system. In particular, it relates to an optical fiber system and a measuring method for accurately measuring the optical parameters of the turbid medium and biological tissue of a body or a living body. Background technique [0002] As optical methods are increasingly used for quantitative diagnosis and treatment monitoring of diseases, researchers or medical personnel often need to know how the irradiated light energy is distributed after entering the patient's organ biological tissue and how to generate reflected and transmitted signals. Except for a few tissues such as the cornea of ​​the eye, the biological tissue of the human body or animal is an optically turbid medium, which means that light absorption and light scattering coexist in the interaction between light and biological tissue. The spatial and temporal distribution of is random in nature. In this case, the energy propagation and distr...

Problems solved by technology

The shortcomings of these methods are either the complexity of the measurement system or the need to leave the sample out of the living body, which cannot be used to accurately determine the optical parameters of the body or the living body
