However, the traditional polarized light imaging technology only uses a certain projection of the polarization state of light as the imaging physical quantity for imaging, and cannot obtain all the polarization information of the target. Or the orientation of the polarizer is different, the obtained images are different, and the obtained information is incomplete. Therefore, it is impossible to judge the change of the target by the change of the image, and even cause misjudgment

Description
Technical field [0001] The invention relates to the field of polarization state measurement and polarization state microscopic imaging, in particular to a polarization state tomography microscopic imaging device and method. Background technique [0002] Polarized light imaging technology is widely used in minerals, chemistry, biomedicine, materials and other disciplines. In recent years, polarized light imaging technology has also made important progress in remote sensing imaging. In the process of target imaging and recognition, for targets with the same color and reflection intensity but different materials, their polarization characteristics are often different. These targets are simple The intensity imaging is basically unrecognizable. Polarized light imaging technology obtains the polarization characteristic image of the object by extracting the polarization information of the light beam after interacting with the substance. It records more information than pure intensity i...
