Abstract:
A light reflection imaging method for acquiring optical parameters and microstructures of tissues in a large area, comprising a turbid medium reflectance calculation method applicable at a random spatial distance and in an entire spatial frequency domain, and a method of measuring the reflectance of a turbid medium at high and low spatial frequencies and inverting the obtained light reflectance to obtain optical parameters of the medium. The inversion method may be a table lookup method or a formula fitting method. The measurement of sub-diffuse and diffuse light reflectance of the turbid medium can be used for measuring the optical properties of the turbid medium and microstructures including a phase function and the like in a large area.
