Embodiment 1
[0025] A hyperspectral imaging measurement system applied to mammary glands with orthogonal square wave frequency encoding, see figure 1 and figure 2 , The imaging measurement system includes: a group of n monochromatic light sources 1 (indicated by LD, the wavelength of the monochromatic light source is between 600-1200nm, this waveband is an "optical window", and the penetration depth is relatively deep) and a camera 4 .
[0026] Wherein, the specific value of n is related to the sensitivity of the breast sample 3 to different wavelengths, which is not limited in the embodiment of the present invention); a group of monochromatic light sources 1 are distributed on one side of the breast tissue sample 3, and a camera 4 is distributed On the other side of breast tissue sample 3.
[0027] Wherein, each monochromatic light source LD in a group of monochromatic light sources 1 1 …LD n Densely arranged on a set hemispherical surface, the lens 2 is used to converge into a beam o...
Embodiment 2
[0050] A hyperspectral imaging measurement system applied to mammary glands with orthogonal square wave frequency encoding, see figure 1 and figure 2 , this embodiment uses a laser diode as a monochromatic light source LD 1 …LD n Take this as an example.
[0051] Each laser diode LD in a group of monochromatic light sources 1 is driven separately by orthogonal square waves of different frequencies i , each pixel in a camera 4 receives each laser diode LD i Monochromatic Light Combination I Through Breast Tissue Sample 3 ij ; Combination of monochromatic light I by computer ij Separation can obtain monochromatic light combination Iij Each laser diode LD in the i Based on the contribution of the breast tissue sample 3, transmission hyperspectral imaging can be performed.
[0052] The computer processing steps in this embodiment are the same as those in Embodiment 1, and will not be repeated here in this embodiment.
