Micro-optical artificial compound eyes [PDF]

Bioinspiration & Biomimetics, 2006
Natural compound eyes combine small eye volumes with a large field of view at the cost of comparatively low spatial resolution. For small invertebrates such as flies or moths, compound eyes are the perfectly adapted solution to obtaining sufficient visual information about their environment without overloading their brains with the necessary image ...

Focusing and imaging with increased numerical apertures through multimode fibers with micro-fabricated optics

, 2013
The use of individual multimode optical fibers in endoscopy applications has the potential to provide highly miniaturized and noninvasive probes for microscopy and optical micromanipulation.

Terahertz Sensing for R/S Chiral Ibuprofen via All-Dielectric Metasurface with Higher-Order Resonance

Applied Sciences, 2021
A terahertz (THz) all-dielectric metasurface with crescent cylinder arrays for chiral drug sensing has been demonstrated. Through the multipole expansion method, we theoretically found that breaking the symmetry of the metasurface can excite higher-order

Non-steady-state extremely asymmetrical scattering of waves in periodic gratings [PDF]

, 2002
Extremely asymmetrical scattering (EAS) is a highly resonant type of Bragg scattering with a strong resonant increase of the scattered wave amplitude inside and outside the grating.

High-resolution polarization-sensitive optical coherence tomography and optical coherence tomography angiography for zebrafish skin imaging

Journal of Innovative Optical Health Sciences, 2021
Zebrafish is an important animal model, which is used to study development, pathology, and genetic research. The zebrafish skin model is widely used in cutaneous research, and angiogenesis is critical for cutaneous wound healing.

Spin‐Decoupled Beam Steering with Active Optical Chirality Based on Terahertz Liquid Crystal Chiral Metadevice

Advanced Materials Interfaces, 2023
Broadband terahertz (THz) chirality and wavefront manipulation play important roles in wireless communication, imaging, and radar systems. In this work, by integrating liquid crystal (LC) into a dielectric metasurface, the gradient phase distribution ...

Design and Print Terahertz Metamaterials Based on Electrohydrodynamic Jet

Micromachines, 2023
Terahertz metamaterials are some of the core components of the new generation of high-frequency optoelectronic devices, which have excellent properties that natural materials do not have. The unit structures are generally much smaller than the wavelength,

Information-Rich Multi-Functional OCT for Adult Zebrafish Intra- and Extracranial Imaging

Bioengineering, 2023
The zebrafish serves as a valuable animal model for both intra- and extracranial research, particularly in relation to the brain and skull. To effectively investigate the development and regeneration of adult zebrafish, a versatile in vivo imaging ...

Demonstration of a simple entangling optical gate and its use in Bell-state analysis [PDF]

, 2005
We demonstrate a new architecture for an optical entangling gate that is significantly simpler than previous realisations, using partially-polarising beamsplitters so that only a single optical mode-matching condition is required.
