TL;DR: In this article, a symmetric inverse-series-connected bimorph actuator with high sensitivity and fast thermal response was proposed for a femtosecond (FSE) EH-micromirror.

TL;DR: A broadband rotary joint for high-speed ultrahigh-resolution endoscopic optical coherence tomography (OCT) imaging in the 800 nm spectral range that features a pair of achromatic doublets in order to achieve broadband operation for a 3 dB bandwidth over 150 nm.

TL;DR: An ultralow-voltage, electrothermal (ET) micro-electro-mechanical system (MEMS) based probe for forward-viewing endoscopic optical coherence tomography (OCT) imaging was reported and its performance was successfully demonstrated with cross-sectional imaging of biological tissues ex vivo and in vivo at a speed up to 200 frames per second.

TL;DR: A new design strategy is introduced for a fiber-optic scanning endomicroscope, where the overall numerical aperture (NA) or beam focusing power is distributed over two stages: a mode-field focuser engineered at the tip of a double-clad fiber (DCF) cantilever to pre-amplify the single-mode core NA, and a micro objective of a lower magnification to achieve final tight beam focusing.

TL;DR: TAD successfully improved the limit of detection (LOD) of target analytes when the target peptides were added to the sample in a concentration close to optimum concentration, and showed that TAD could achieve LOD improvements on an average of 3-fold in a simple and 2- fold in a complex sample.
