Neural Research on Visual Fatigue in Virtual Reality

A recent study published in Brain Sciences investigates the fundamental neural mechanism of stereoscopic visual fatigue in virtual reality.

How Multimodal Imaging Helps Differentiate Between Mechanisms of Outer Retinal Damage

A recent study published in Diagnostics identifies multimodal imaging traits to distinguish primary inflammatory choriocapillaropathies, such as multiple evanescent white dot syndrome and idiopathic multifocal choroiditis, from primary photoreceptoritis.

Monitoring Snow Cover with Optical Remote Sensing

A recent study published in Remote Sensing investigates the potential of remote sensing time series to anticipate the snow line elevation in the European Alps. The researchers produced snow line elevation time series using data from the entire Landsat archive in 43 Alpine catchments.

Non-Linear Radiation Forces and Confinement of Neutral Particles into the Pulse Envelope

A pre-proof study of Optik explains analytical formulas of the non-linear radiation forces and potential densities resulting from a laser pulse traveling in a dielectric medium.

Study Presents Conditional Random Field-Guided Multi-Focus Image Fusion Method

A recent study published in the Journal of Imaging presented a conditional random field-guided fusion technique. The Edge Aware Centering method was used to excerpt the high and low frequencies of images.

Study Introduces Low-Cost Optical Sensors for Harsh Environments

A recent study published in Micromachines describes the design, fabrication, and testing of a silicon inertial optical sensor for low-frequency (less than 2 kHz) applications. The researchers used finite element analysis parameterization to consider different accelerometer designs.

How Coherent Oscillations Affect the Development of Turbulent Flame Brush

Influences Behind Evolution of the Turbulent Flame Brush

Studying how coherent oscillations of various amplitudes can affect the development of turbulent flame brush in a bluff body is the main goal of a recent study.

Controlling Intraocular Particles Without Harming the Cornea

A recent study describes a brand-new technique that uses acoustic waves to alter intraocular particles without entering the anterior chamber and causing harm to the cornea.

Study Proposes LED Hyperspectral Imaging for Biomedical Applications

A recent study published in Sensors proposes a unique laboratory hyperspectral imaging system designed for biomedical optics.
