A study published in Water estimated the velocity field in highly aerated flow over a stepped spillway without sidewall constrain using the Bubble Image Velocimetry (BIV) method.
A recent study in Energies reviews the key characteristics of an optical encoder's accuracy, resolution, and repeatability. The experimental reading head for a Moiré effect-based linear optical encoder is utilized to investigate the impact of various reading head designs on an optical encoder's performance under varied mounting errors and dynamic circumstances.

A recent study published in Chemosensors presents a unique donor-p-acceptor luminous dye as a sensor for Cu2+ ions. The 3,5-diphenyl-dicyanomethylene-4-H-pyran (DCM) that makes up the fluorophoric core has extended styryl chains at positions 2 and 6 for metal coordination and is used for copper (II) detection.

In an article published in the journal Sensors, researchers have developed a fiber optic humidity sensor using a leakage mode that enables measurements at low humidity.
Teledyne Princeton Instruments, part of Teledyne’s Vision Solutions Group, announced today that its COSMOS camera was recognized among the best by the 2022 Laser Focus World Innovators Awards.
In an article published in Remote Sensing, researchers have analyzed the properties of various profiles of atmospheric refractive index structure constant over the Lhasa Region. The valuable in situ sounding data necessary for the analysis were collected at different strength conditions of an Asian summer monsoon anticyclone (ASMA) in August 2018.

The time it takes to manufacture fibre-optic medical devices used in healthcare has been dramatically slashed, Heriot-Watt University has announced.
This demonstration highlights the potential for RE elements to produce stable multiband lasing.
Applications like full-color displays, optical communications, and computation all depend on microlasers with many lasing bands. The plentiful long-lived intermediate energy levels and intraconfigurational transitions provided by rare earth (RE) elements are essential for emissions over a variety of lightwave bands.
In an article published in Remote Sensing, researchers used geostatistical analysis, low-density airborne laser scanning (ALS) metrics, and forest inventory data to estimate old-growth indices (OGIs) as indicators of old-growth forest conditions.
In an article published in Biosensors, researchers have constructed a disposable, flexible, simple and cost-effective colorimetric film sensor to rapidly detect gaseous ammonia.
A ZnO-coated optical fiber sensor for detecting a volatile organic compound biomarker for diabetes has been recently demonstrated in a study published in Sensors. The researchers used a coreless silica fiber (CSF) coupled with single-mode fiber (SMF) at both ends to synthesize the SMF-CSF-SMF structure.
