Abstract
The invention discloses a hyperspectral imaging measurement system applied on sinusoidal wave frequency coding of a breast. A set of monochromatic light sources are distributed at one side of a breast tissue sample. Cameras are distributed at the other side of the breast tissue sample. The monochromatic light sources in the set of monochromatic light sources are densely arranged on a semi-spherical surface. The light which is emitted from the monochromatic light sources is gathered to a light beam by means of a lens, thereby forming a light source. The cameras form a light receiving device. Sinusoidal waves with different frequencies are used for respectively driving the monochromatic light sources in the set of monochromatic light sources. Each pixel point in an image which is received by the cameras is a combination of monochromatic light that is emitted from the monochromatic light sources and pass through the breast. A computer separates the combination of the monochromatic light for obtaining the contribution of each monochromatic light source in the set of monochromatic light sources, thereby realizing transmission hyperspectral imaging of the breast. The hyperspectral imaging measurement system realizes high-precision measurement for breast transmission hyperspectral imaging with large information amount in high speed. Furthermore the hyperspectral imaging measurement system has advantages of low cost, convenient application, etc. The hyperspectral imaging measurement system is suitable for daily household self measurement.
