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 triangular wave frequency coding high spectral imaging measurement system applied to a mammary gland. A group of monochromatic light sources are distributed on one side of a mammary tissue sample, cameras are distributed on the other side of the mammary tissue sample, all the monochromatic light sources in the group of monochromatic light sources are densely arranged on one hemispherical surface and collected into a beam of light by a lens to form a light source, a light source receiving device comprises the cameras, triangular waves with different frequencies and a two-time ratio relationship respectively drive all the monochromatic light sources in the group of monochromatic light sources, each pixel point in an image received by the cameras is a monochromatic light combination with each monochromatic light source penetrating the mammary gland, and a computer separates the monochromatic light combination to obtain the contribution of each monochromatic light source in the monochromatic light combination, so that transmission high spectral imaging for the mammary gland is realized. The system realizes high-speed and high-information mammary gland transmission high spectral imaging high-precision measurement, has the advantages of low cost, convenience on application and the like, and is suitable for regular family self-inspection.
