Impacts of particle morphology and rotation on optical manipulation
Light: Science & ApplicationsIt is well known that nonspherical particles rotate continuously in light beams, with their rotation directions determined by the light spin. Here, we reveal that particle morphology (e.g., size, shape, length, etc.) and rotation angle are vital in ...

Combination of hanger reflex and optical flow enhances head rotation and influences its direction
Frontiers in Virtual RealityThe Hanger Reflex (HR) is a tactile illusion phenomenon in which involuntary head rotation occurs when a person wears a wire hanger on the head. This rotation is induced by skin deformation caused by pressure on the head, and can occur in multiple ...
