Techniques and Advances in Ultrafast Photography

open access: yesAdvanced Photonics Research, Volume 6, Issue 12, December 2025.
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, Volume 6, Issue 12, December 2025.
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

A Holographic Sensor‐Integrated Deep Learning Framework for Noninvasive Assessment of Stored Red Blood Cell Quality

open access: yesAdvanced Sensor Research, Volume 4, Issue 12, December 2025.
A holographic sensing‐integrated deep learning platform enables real‐time, label‐free assessment of red blood cell (RBC) quality during storage. By combining diffusion model‐based data augmentation and self‐supervised pretraining, the framework achieves high segmentation accuracy with minimal data.
