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.

Claim (Index 4):
The light reflection imaging method for acquiring optical parameters and microstructures of tissues in a large area according to  claim 3 , wherein, assuming that p Forward (\u03b8) satisfies Gaussian distribution, the random phase function p(\u03b8) of the scattering medium is modified into: p SAA \ue8a0 ( \u03b8 ) = 1 - 2 \ue89e \ue89e p b \u03c0\u0398 2 \ue89e exp \ue8a0 ( - \u03b8 2 \u0398 2 ) + 1 2 \ue89e \u03c0 \ue89e p b , from which p b = 2 \ue89e \u03c0 \ue89e \u222b \u03c0 / 2 \u03c0 \ue89e p \ue8a0 ( \u03b8 ) \ue89e sin \ue89e \ue89e \u03b8 \ue89e \ue89e d \ue89e \ue89e \u03b8 and \u03b8 2 = 2 \ue89e \u03c0 1 - 2 \ue89e \ue89e p b \ue89e \u222b 0 x \ue89e p \ue8a0 ( \u03b8 ) \ue89e \u03b8 2 \ue89e sin \ue89e \ue89e \u03b8 \ue89e \ue89e d \ue89e \ue89e \u03b8 are obtained, and through p iso =2p b , the SAA diffusion function is transformed into S \ue8a0 ( q , z ; s \u22a5 0 ) = exp \ue8a0 ( - iq \u00b7 s \u22a5 0 \ue89e z ) \ue89e exp [ - \u03bc t \ue89e z + ( 1 - 2 \ue89e \ue89e p b ) \ue89e \u03bc s \ue89e \u03c0 \ue89e erf \ue8a0 ( 1 2 \ue89e \u0398 \ue89e \ue89e qz ) \u0398 \ue89e \ue89e q ] .
