Problems solved by technology

[0002] In the prior art, imaging the interior of objects, especially the interior of the human body, has the outstanding advantages of being non-destructive, non-invasive, and non-radiative through light, but so far there is no mammary gland transmission imaging optical measurement system that can be used at home for frequent tumors Self-inspection, the reason is that the existing breast imaging measurement system has high cost, complex operation, and limited accuracy, which cannot meet the needs of breast self-inspection in practical applications

Abstract

The invention discloses a hyper-spectrum chart imaging measuring system applied to mammary gland and based on orthogonal square wave frequency coding. A set of monochromatic sources are distributed at one side of a mammary tissue, and a camera is distributed at the other side of the mammary tissue. All monochromatic sources in the monochromatic source set are densely arranged on one arranged hemispherical face, a beam of light is formed in a converged mode by the adoption of a lens, and therefore a light source is formed. The camera forms a light source receiving device. Orthogonal square waves with different frequencies are adopted to drive all the monochromatic sources in the monochromatic source set respectively, and each pixel in a chart received by the camera is a monochromatic source combination of each monochromatic source passing through the mammary gland. A computer separates the monochromatic source combinations to obtain the contribution of each monochromatic source in the monochromatic source set, and hyper-spectrum chart imaging of the mammary gland is achieved accordingly. The hyper-spectrum chart imaging measuring system applied to the mammary gland and based on orthogonal square wave frequency coding achieves high-accuracy measurement of high-speed and big-information hyper-spectrum chart imaging. In addition, the hyper-spectrum chart imaging measuring system applied to the mammary gland and based on orthogonal square wave frequency coding has the advantages of being low in cost, convenient to apply and the like, thereby being suitable for frequent filmily self-inspection.
