Special Issue Information

Dear Colleagues,

Some materials have unique optical properties (such as refractive index, reflectance, absorbance, band gap, photoluminescence, and transmittance) due to their special structures. To characterize and evaluate these properties, various optical imaging and detection methods have been developed to provide abundant spatial and spectral information.

Modern optical techniques can provide functional and molecular information with high spatial resolution, deep penetration, enhanced temporal responsiveness, and improved chemical specificity. In recent years, these techniques have been increasingly tailored for characterizing materials and probing their interactions with biological tissues. Here, in this Special Issue, we aim to collect papers covering the latest progress of advances in both optical modalities and new applications in characterizing material properties.

The optical principles and methods used to evaluate the performance of emerging materials in different physical conditions will be of valuable reference for the researchers working in the material science field. Notable research works also include theories and models relating linear and nonlinear optical properties to those of the constituent materials and to the morphology of the composite structure.

This Special Issue, “Optical Imaging and Detection Applied in Characterizing Material Properties”, pays attention to the combination of material properties and optical analysis. Topics of interest include, but are not limited to: optical experiments and theoretical studies relating to material science; optical monitoring during material manufacturing and processing; microscopic to macroscopic material analysis; and performance verification techniques.

It is my pleasure to invite you to submit a manuscript for this Special Issue. Various advances in optical imaging and detection systems, modeling and simulation, theoretical calculation, and application demonstration on the optical characterization of material properties are welcome.

Safety of the observation window is one of the core concerns for manned submersibles. When subjected to underwater static pressure, extrusion and creep deformation always occur in the observation window, which can pose a threat to both safety and optical performance. To assess the deformation, real-time and non-contact monitoring methods are necessary. In this study, a conceptual setup based on the waveplate rotation and dual-DoFP (division of focal-plane polarimeter) polarization camera is built for the observation window’s creep monitoring by measuring the Mueller matrix images of the samples under different pressures and durations. Then, a series of characteristic parameters, such as t1, R, r, R′, are extracted from the Muller matrix images by Mueller matrix transformation (MMT), Mueller matrix polar decomposition (MMPD), correlation analysis and phase unwrapping method. The results demonstrate that these parameters can effectively describe the observation window’s creep at different pressure levels which are simulated by finite element analysis. Additionally, more characterization parameters, such as ψ, A and D, are given from the Mueller matrix images and discussed to illustrate the method’s potential for further applications and investigations. Ultimately, future devices based on this method could serve as a valuable tool for real-time and non-contact creep monitoring of the submersible observation windows. Full article

A method for ultrafast time-resolved four-channel Jones matrix measurement of birefringent materials using an ultrafast laser is investigated. This facilitated the acquisition of a four-channel angular multiplexing hologram in a single shot. The Jones matrix information of a birefringent sample was retrieved from the spatial spectrum of a hologram. The feasibility of this approach was established by measuring the Jones matrix of starch granules in microfluidic chips and the complex amplitude distribution and phase delay distribution of liquid crystal cell at different voltages. Moreover, when the picosecond laser was switched to a femtosecond laser, ultrafast measurements were possible provided that the time interval between two detection pulses was larger than the pulse width.
