Fixed-Time Convergent Guidance Law with Impact Angle Control

Complexity, 2020
The existing convergence control guidance laws are designed via the Lyapunov asymptotic stability theory or finite-time stability theory. However, guidance law based on the Lyapunov asymptotic stability theory would lead the states to zero only as time ...

Fourier multispectral imaging

Optics Express, 2015
Current multispectral imaging systems use narrowband filters to capture the spectral content of a scene, which necessitates different filters to be designed for each application. In this paper, we demonstrate the concept of Fourier multispectral imaging which uses filters with sinusoidally varying transmittance.

TRIM: Simultaneous Thermometry, Ranging, and Imaging via a Monolithic Metalens

Advanced Science, EarlyView.
ABSTRACT While metasurfaces offer a pathway beyond the discrete architectures of conventional LWIR systems, physically fusing high‐precision thermometry and passive ranging onto a single metalens remains a formidable challenge. Here, we demonstrate a monolithic, dual‐focus metalens capable of simultaneous multidimensional sensing.

A Coordination Law for Multiple Air Vehicles in Distributed Communication Scenarios

Journal of Advanced Transportation, 2020
This paper proposes a consensus-based guidance methodology for multiple air vehicles to arrive at the same spot cooperatively. First, based on the Lyapunov stability theory, a guidance law with only one control parameter is proposed, and the exact ...

Wavelength‐Dependent Photobiomodulation Regulates Macrophage Polarization via Mitochondrial Dynamics and Metabolic Reprogramming

Advanced Science, EarlyView.
Light wavelength encodes distinct macrophage fates through mitochondrial and metabolic remodeling. Red 625 nm irradiation induces glycolysis, mitochondrial fission, and M1 polarization, whereas near‐infrared 850 nm irradiation promotes fatty acid oxidation, mitochondrial fusion, and M2 polarization.
