. The field-enhancement is defined as the ratio of the optical near-field at the nanotriangle tip near the nano-gap (referred to as the “tip” in the following), averaged over the curved surface defined by the tip radius of curvature and gold thickness, to the optical field of the ...
Fortunately, as the light field propagates, the phase delay also causes changes in the amplitude distribution; therefore, we can record the amplitude of the propagated light field and then calculate the corresponding phase. This operation generally comes under different names according to the applicati...
voice recognition; an infrared, color, stereoscopic, and/or depth camera for machine vision and/or gesture recognition; a head tracker, eye tracker, accelerometer, and/or gyroscope for motion detection and/or intent recognition; as well as electric-field sensing componentry for assessing brain ...
It introduces three additional weighting mechanisms to use the information of feature map in space, time, and space–time to achieve weighting to increase the receptive field, and maximize the retention of the information extracted by the backbone feature [19]. The calculation principle diagram is ...
Off-axis annular detector imaging was used for dark-field (Z-contrast) imaging and atomic-resolution imaging. Compositional analysis by X-ray emission detection was also conducted. For energy-dispersive X-ray spectroscopy, a Bruker 5030 SDD detector with a window area of 30 mm2 was used. All ...

In a nonemissive LCD, its CR is limited by the depolarization effect mainly from the employed LC material, surface alignment and CFs74,75. Normally, the CR of an LCD is approximately 5000:1, 2000:1 and 1000:1 for the multidomain vertical alignment (MVA) mode36, fringe-field switching (...
Plasmonic skyrmions: The first method to construct the vector texture is using the electric field of evanescent waves on surface plasmon polaritons (SPP). By sculpturing structured gratings as a confined region on a metal film, the SPP field can form geometric standing wave fulflling the skyrmion...
A camera has a lens and aperture device for determining 3D information. A projector projects an optical pattern toward a surface. The camera has at least two off-axis apertures ther
