The Correction Method for Wavefront Aberration Caused by Spectrum-Splitting Filters in Multi-Modal Optical Imaging System

Photonics
In current biomedical and environmental detection, multi-modal optical imaging technology is playing an increasingly important role. By utilizing information from dimensions such as spectra and polarization, it reflects the detailed characteristics and ...

Polarization analysis of a balloon-borne solar magnetograph [PDF]

, 1993
The 10(exp -5) polarization specification for the Balloon-borne Vector Magnetograph (BVM) can be met. The 10(exp -5) specification is shown to be a limitation on the diattenuation and retardance along the chief ray path through the optical system, such ...

Properties of silicon integrated photonic lenses:bandwidth, chromatic aberration, and polarization dependence

, 2013
We analyze the properties of silicon integrated photonic lenses based on scattering optical elements. The devices have been inverse-designed by combining genetic algorithms and the multiple scattering theory.

Demo 24-05 Polarization by Reflection

, 2001
Light waves can be polarized by reflection from a dielectric surface, as shown in Figure 1. The amount of polarization depends on the angle at which the light strikes the surface, with the maximum effect occurring at an angle called the Brewster angle,

Aberration-corrected hybrid metalens for longwave infrared thermal imaging

Nanophotonics
Wide-angle metalenses in the longwave infrared have shown great advantages over the traditional refractive doublets or triplets, due to light weight, CMOS compatibility, and low cost.

Design of Terahertz Polarization-Multiplexed Structured Light Metasurface Based on Particle Swarm Optimization

Photonics
We propose a terahertz achromatic polarization-multiplexed structured light metasurface based on the particle swarm optimization (PSO) algorithm, operating from 0.8 to 0.95 THz.

Demo 22-21 Spherical Aberration

, 2001
A lens that has a spherical shape will exhibit spherical aberration; the position at which parallel light rays focus is closer to the lens for rays further away from the optic axis. When a stop is placed over the outer part of the lens and the distance

Polarization Aberrations [PDF]

, 1990
The analysis of the polarization characteristics displayed by optical systems can be divided into two categories: geometrical and physical. Geometrical analysis calculates the change in polarization of a wavefront between pupils in an optical instrument.

Observation of the Impact of Dislocations on Atomic Polarization and Domain Structures in BaTiO3

Advanced Physics Research
Line defects, dislocations, in ferroelectric materials can facilitate the nucleation of new domains and pin the motion of domain walls, leading to significant electromechanical responses.
