Detection of orbital angular momentum carried high-order radial vortex
For the high-order vortex beam carrying OAM modes, the CNN-OAM mode classifier has an average detection accuracy of 97.3% and can detect up to 30 OAM modes under any AT intensities ranging from 1 × 10 −16 m −2/3 to 1 × 10 −14 m −2/3 at a propagation distance of 1000 m. The great accuracy and extensive detection range of the CNN-OAM ...

Generation of spiral optical vortex with varying OAM for …
Here we propose a concept of the spiral optical vortex (SOV) which contains multiple OAM modes from inside to outside along the spiral intensity field. Theoretically, by linking the azimuthal spiral phase with the beam radius, the SOV can be generated. The corresponding OAM spectrum of the SOV are analyzed theoretically and measured experimentally.

Spiral Classifier for Mineral Processing
Spiral classifier. Another mechanical classifier is the spiral classifier. The spiral classifier such as the Akins classifier consists of a semi-cylindrical trough (a trough that is semicircular in cross-section) inclined to the horizontal. The trough is provided with a slow-rotating spiral conveyor and a liquid overflow at the lower end.
