Adaptive time resolved correlation technique for non-equilibrium dynamics of epoxy resin curing evaluation
The time-resolved correlation technique is a standard approach for examining the intricate microscopic dynamics within polymeric materials. Nonetheless, its traditional application falls short in providing the real-time tracking capabilities required for monitoring the dynamic progression effectively. In this study, we propose adaptive time resolved correlation technique to observe the progression of microscopic dynamics during epoxy resin curing. By employing an adaptive processing method with a scheme for baseline auto-determination and the shortest delay time adjustment, the acquisition of intensity autocorrelation function is adjusted to accommodate the evolving dynamics of the system. Then the function can be well fitted to a standard model, which can reveal the system dynamics influenced by non-equilibrium factors such as internal stress relaxation and the cross-linking network. It is believed that the adaptive time resolved correlation technique effectively characterizes the progression of microscopic dynamics and holds potential as an online monitoring technique.
期刊介绍:
Optics and Lasers in Engineering aims at providing an international forum for the interchange of information on the development of optical techniques and laser technology in engineering. Emphasis is placed on contributions targeted at the practical use of methods and devices, the development and enhancement of solutions and new theoretical concepts for experimental methods.
Optics and Lasers in Engineering reflects the main areas in which optical methods are being used and developed for an engineering environment. Manuscripts should offer clear evidence of novelty and significance. Papers focusing on parameter optimization or computational issues are not suitable. Similarly, papers focussed on an application rather than the optical method fall outside the journal''s scope. The scope of the journal is defined to include the following:
-Optical Metrology-
Optical Methods for 3D visualization and virtual engineering-
Optical Techniques for Microsystems-
Imaging, Microscopy and Adaptive Optics-
Computational Imaging-
Laser methods in manufacturing-
Integrated optical and photonic sensors-
Optics and Photonics in Life Science-
Hyperspectral and spectroscopic methods-
Infrared and Terahertz techniques
