Distributed Strain Measurement Using Power-Based Brillouin Sensor with Three Folded Dynamic Range

open access: yesProceedings, 2019
We clarify that, unlike time-domain techniques, slope-assisted Brillouin optical correlation-domain reflectometry has a trade-off relation between the strain dynamic range and the spatial resolution.

High Dynamic Range Fluorescence Imaging [PDF]

open access: yesIEEE Journal of Selected Topics in Quantum Electronics, 2019
Fluorescence acquisition and image display over a high dynamic range is highly desirable. However, the limited dynamic range of current photodetectors and imaging CCDs impose a limit on the fluorescence intensities that can be simultaneously captured during a single image acquisition.
