The embodiments of the present invention disclose a method, system, device and electronic apparatus for measuring concentration of water and lipids components. The method includes acquiring an optical absorption coefficient of a sample to be measured irradiated by a light source of at least two wavelengths, wherein a wavelength of the light source of at least two wavelengths is not greater than 1000 nm; and acquiring an extinction coefficient of water irradiated by the light source of at least two wavelengths and an extinction coefficient of lipids irradiated by the light source of at least two wavelengths; determining a concentration of water in the sample to be measured and a concentration of lipids in the sample to be measured, respectively, based on the optical absorption coefficient of the sample to be measured irradiated by the light source of at least two wavelengths, the extinction coefficient of water irradiated by the light source of at least two wavelengths, and the extinction coefficient of lipids irradiated by the light source of at least two wavelengths.

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.
