21 It is also worth noting that, due to the photostability of the NV centers and the possibility to locate the same NV repeatedly, it should also be possible to perform 1D measurements whilst rotating the line-shaped minimum around the optic axis after each scan, in order to record images with uniform 2.4 nm focal plane resolution.
The focal spot resolutions of the time reversal estimates are also evaluated.
Physical quantities such as momentum resolution, focal plane size and inclination are explicitly represented as functions of transport matrix elements.
Standard ultrasound imaging techniques rely on sweeping a focused beam across a field of view; however, outside the transmission focal depth, image resolution and contrast are degraded.
Numerical results demonstrate that the best performance is obtained for the case of the GRIN metalens in terms of the focal position, transversal resolution and thickness, reducing its volume up to ∼52.3% with respect to the smooth-profiled plano-concave metalens.
Despite limited resolution, focal uptake of tracers can be seen in small structures on in vivo scans as 'beacons.' The strength of the signal and ability to see it depend on the number of binding sites for the probe as well as attenuation and scatter from adjacent activity.
At the current focal distance, the resolution is enough to distinguish lateral root primordia.
Yet, since the image formation purely relies on the optical focus, when the target object is located outside the focal zone, imaging resolution degrades dramatically (e.g. 0.1 mm off the focus the beam size might expand to 0.1 mm and more).
Voyager 1's Imaging Science Subsystem (ISS), now disabled, consisted of two cameras: a 200 mm focal length, low-resolution wide-angle camera (WA), used for spatially extended imaging, and a 1500 mm high-resolution narrow-angle camera (NA) – the one that took Pale Blue Dot – intended for detailed imaging of specific targets.
Typically, the former uses a single large-aperture lens system and a large, high-resolution focal plane array; the latter uses many small-aperture lenses, each coupled to a small group of photodetectors.
