Optical techniques are experimental and analytical methods that exploit the generation, manipulation, and detection of electromagnetic radiation in the ultraviolet, visible, and infrared ranges to probe material properties, structures, and dynamics. They encompass approaches such as absorption, fluorescence, Raman and elastic scattering measurements, interferometry, and imaging modalities that rely on well-defined light–matter interactions. These techniques enable quantitative characterization of refractive indices, absorption coefficients, energy level structures, molecular conformations, and nanoscale morphology, often with high spatial and temporal resolution. Optical techniques are widely integrated with spectroscopy, microscopy, and metrology platforms and can be implemented in both far-field and near-field configurations.
A KAIST research team led by professor Mooseok Jang from the Department of Bio and Brain Engineering has developed a single-shot phase imaging technique that reconstructs a phase object—a transparent object such as glass, ...
