Precise Real‐Time Measurement of Liquid Viscosity Using Digital Video Data

Advanced Intelligent Systems, EarlyView.
Frame‐by‐frame image similarity analysis is employed to obtain the viscosity of moving liquids in real time. The method allows for online implementation even in harsh environments, replacing complex and invasive experiments. Quantitative knowledge of liquid viscosity is of fundamental importance in many areas of materials synthesis and processing ...

Deep Tissue Wavefront Estimation for Sensorless Aberration Correction

MATEC Web of Conferences, 2015
The multiple light scattering in biological tissues limits the measurement depth for traditional wavefront sensor. The attenuated ballistic light and the background noise caused by the diffuse light give low signal to noise ratio for wavefront ...

Adaptive Compound Eye Imaging Device Based on Electrowetting Liquid Aperture with Adjustable Shape

Advanced Intelligent Systems, EarlyView.
Artificial compound eye technology enables imaging with a large field of view. However, the lack of adjustability limits its applications. An adaptive compound eye imaging device based on electrowetting liquid aperture with adjustable shape is proposed to achieve both large field‐of‐view imaging and adaptive imaging, including light intensity ...
