Description

technical field [0001] The invention relates to a non-contact and on-line measurement method for the form of molten material in a molding device, in particular to a method for measuring tomographic images of the form of molten material in a sealed chamber. Background technique [0002] Understanding the detailed and complete morphological changes and thermal history factors that affect the shape of molten polymers during processing can not only guide people to focus on the "order, structure, and structure of crystalline and amorphous polymers" under dynamic and static (equilibrium) conditions. And shape" changes, and more practically, it can be used as a theoretical basis to control the polymer structure and improve the quality of polymer molded products. So far, there are direct observation method, flow birefringence method, laser Doppler velocimetry, electron microscope micro-area, x-ray diffraction, laser speckle photography and visualization technology for the shape meas...
