Toward High Altitude Airship Ground-Based Boresight Calibration of Hyperspectral Pushbroom Imaging Sensors

open access: yesRemote Sensing, 2015
The complexity of the single linear hyperspectral pushbroom imaging based on a high altitude airship (HAA) without a three-axis stabilized platform is much more than that based on the spaceborne and airborne.

Dual Mach-Zehnder Interferometer Based on DCF and FCF for Temperature and Strain Measurement

open access: yesPhotonic Sensors
In this paper, a dual Mach-Zehnder interferometer for measuring both temperature and strain is proposed and verified by experiments. The sensor configuration involves cascading a four-core fiber and a double-clad fiber between two single-mode fibers.

Robust OAM-SK FSO demodulation under strong turbulence via Vision Transformer and Polar code integration

open access: yesResults in Physics
This paper proposes a joint demodulation and decoding scheme for orbital angular momentum shift keying free-space optical (OAM-SK-FSO) communication systems, termed ViT-Polar, which deeply integrates a Vision Transformer (ViT) with Polar coding to ...

Dynamical redistribution of quantum resources in tree-level Bhabha scattering

open access: yesPhysics Letters B
The fundamental interactions governed by quantum electrodynamics (QED) are intrinsically rich in quantum resources, yet how these resources dynamically redistribute during relativistic scattering is still not fully understood.
