Abstract: A method for optical property measurement based on spatial frequency domain imaging, includes: obtaining a first target sinusoidal light pattern with a specified spatial frequency by modulating first light emitted by a light source in a spatial frequency domain, the number of coded bits of the first target sinusoidal light pattern is smaller than a preset number of bits; irradiating the first target sinusoidal light pattern to a surface of a sample to be detected; collecting light intensity distribution data of second light, the second light is formed after the first target sinusoidal light pattern is reflected by the sample to be detected; determining one or more optical property parameters of the sample to be detected according to the light intensity distribution data of the second light.

Abstract: An imaging system for measuring water and blood lipid content in a tissue sample includes a light source configured to emit a plurality of sequential wavelengths of light within a predetermined range of wavelengths, a spatial modulation device configured to direct each of the plurality of sequential wavelengths of light onto a tissue sample plane to generate a first plurality of patterns on the issue sample plane at a first spatial frequency and a second plurality of patterns on the tissue sample plane at a second spatial frequency, an imaging device configured to generate first image data reproducible as images the first plurality of patterns and second image data reproducible as images the second plurality of patterns, and a controller configured to determine a first optical property and a second optical property for each location on the sample plane.
