Advancing Clinical Medicine with Raman Spectroscopy: Current Trends and Future Perspectives

open access: yesAdvanced Photonics Research, EarlyView.
Raman spectroscopy and microscopy may become excellent tools in clinical medicine, including hematology, oncology, infectious diseases, neurology, gastroenterology, reproductive medicine, rheumatology, and cardiovascular research. However, many challenges such as signal interference, standardization issues, and limited clinical application need to be ...

High‐Speed, Continuous, Large‐Angle Nonmechanical Beam‐Steering with Liquid Crystal Etalons

open access: yesAdvanced Photonics Research, EarlyView.
Liquid crystal (LC) is a strong candidate material for nonmechanical beam‐steering devices. This study proposes a new approach using three components: a superluminescent diode (SLD), an LC etalon, and a grating. Broad‐spectrum light from the SLD is passed through the LC etalon, generating wavelength‐swept light.

Techniques and Advances in Ultrafast Photography

open access: yesAdvanced Photonics Research, EarlyView.
This review maps the fast‐growing field of ultrafast photography from early mechanical cameras to modern optical‐computational methods. It organizes techniques into four families (multishot passive/active; single‐shot passive/active), explains how they reach trillion‐frame‐per‐second speeds, compares capabilities and tradeoffs, and highlights ...

Displacement and Vibration Measurements with Interferometers: Benchmark Configurations, Performance, and R&D Opportunities

open access: yesAdvanced Photonics Research, EarlyView.
Self‐mixing interferometry is a powerful technique that brings together the exceptional sensitivity of phase measurements with the unequalled simplicity of the self‐mix configuration based on modulation of the cavity field induced by the return from the target. According to the selected measurand, displacement or vibration, and to the analog of digital
