All-fiber high-speed image detection enabled by deep learning
Nature Communications, 2022 Here, the authors demonstrate high-speed imaging through multimode optical fibers by using the high intermodal dispersion to transform 2D spatial information into 1D temporal pulsed signal streams.

Cascaded Dual-Soliton Pulse Stokes for Broadband Coherent Anti-Stokes Raman Spectroscopy
IEEE Photonics Journal, 2016 We report a spectrally and temporally cascaded dual-soliton Stokes excitation source for broadband coherent anti-Stokes Raman spectroscopy (CARS) based on a single Yb-doped fiber laser.

Implementation of ultrasonic sensing for high resolution measurement of binary gas mixture fractions [PDF]
, 2014 We describe an ultrasonic instrument for continuous real-time analysis of the fractional mixture of a binary gas system. The instrument is particularly well suited to measurement of leaks of a high molecular weight gas into a system that is nominally ...

Reproducibility of electrical caries measurements: A technical problem? [PDF]
, 2005 The currently available instrument for electrical detection of occlusal caries lesions {[}Electronic Caries Monitor (ECM)] uses a site-specific measurement with co-axial air drying. The reproducibility of this method has been reported to be fair to good.

Study on Flow Control and Noise Reduction of Jet-type Centrifugal Pump based on Non-smooth Surface Structure [PDF]
Journal of Applied Fluid MechanicsJet-type centrifugal pumps are widely used in daily water supply systems due to their excellent self-priming capabilities; however, their complex internal flow patterns can negatively affect performance and generate high noise levels.

Application of aerosol electrometer for ambient particle charge measurements [PDF]
, 2008 The charge on ambient atmospheric particles is an important parameter in the investigation of particle dynamics. Yet, there is only limited knowledge available on it, mainly due to the lack of instrumentation for its direct measurement.
