Description

technical field [0001] The invention relates to the fields of polarization state measurement and polarization state microscopic imaging, in particular to a polarization state tomographic 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 those targets with the same color and reflection intensity but different materials, their polarization characteristics are often different. are largely unrecognizable in intensity imaging. The polarized light imaging technology obtains the polarization characteristic image of the object by extracting the polarization information of the light beam that interacts with the material, which records more information than pure intensity imaging, and...

Problems solved by technology

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
