By tuning the chemical potential of graphene in the first (G1) and second (G2) layers, control of reflected and transmitted waves is attainable real-time, along with manipulation of the EM wavefront. For reflection and transmission modes, control of the phase layer enables the attainment of ...
Note that the definition of numerical aperture is not based on the focal length for lenses or objectives which are designed for imaging from some object plane to an image plane. Here, the angular opening is considered from a point in the object plane. See the article on numerical aperture fo...
Visitron Systems, GmbH). Imaging was performed using a ×10 water-immersion objective (Zeiss, NA 0.3) at a rate of one frame per 2 min over 120 min in total, starting at 6 hpf. Three focal planes
where f = 430 μm is the focal length of the cylindrical metalens. As shown in Fig. 5a, the simulated phase profile agrees well with the theoretical one under the XLP illumination. The theoretical and simulated cross-section intensity distributions on the xoz plane are shown in Fig. 5b...
APERTIF, a focal plane array instrument, currently being commissioned, uses 12 dishes of the Westerbork Synthesis Radio Telescope [36]. Each focal plane array holds 121 Vivaldi elements. Most recently the Low Noise Tile prototypes have been built to further decrease the receiver noise figure of ...
Moving towards the southern margin of the transect, the second syncline that characterizes these hilly reliefs still folds the Messinian-Pleistocene marine deposits of the FCO and the FAA, which rest unconformably above the RAN. 4.5. Field evidence for recent deformation In the following section we...
An example of such a device is schematically shown in Figure 4B, where a lens is designed to have the same focal length at the red, blue, and green wavelengths [167]. This method can also be applied to conventional diffractive elements. The second method of multiwavelength design is ...
, focal length , exit pupil aperture diameter –and factor , the ratio of the length of the relevant side of the working pupil plane to . affects the sampling pitch in the image plane, with the effective f-number, in a way that can be intuitively related to the size of an Airy Disk...
By adjusting the voltage applied to the VFL, the axial position of focal plane of the probe beam could be placed to a specific location in retinal structure, followed by WSAO optimization at that particular depth of focus to enhance resolution of the Scientific Reports | 6:27620 | DOI: ...
To see it more clearly, let the image captured at the original mask plane be I1(r) = |A(r)|2, and the second image captured at the original sensor plane be I2(r) = I(r), then Eq. (12) can be reformulated as:...
