Spin-Dependent Optical Geometric Transformation for Cylindrical Vector Beam Multiplexing Communication

ACS Photonics, 2018
Given by the Shannon theorem, the data rate in a single mode fiber is approaching the capacity limit of 100 Tbit/s, which even applies to all existing wavelength division multiplexing and advanced modulation formatting techniques.

Human-Like Trajectory Planning for Autonomous Vehicles Based on Spatiotemporal Geometric Transformation

IEEE transactions on intelligent transportation systems (Print), 2022
Human-driven vehicles and different levels of autonomous vehicles are expected to coexist on roads in the future. However, autonomous systems behave differently from their human-driver counterparts, these two behaviors are incompatible with one another ...

Geometric transformation modeling for line-scan images under different camera poses

Optical Engineering: The Journal of SPIE, 2022
. Geometrically aligning two images is a basic image process in the machine vision field. In general, the geometric transformation model is selected according to the complexity of the geometric transformation between images, and the type of camera that ...
