The product's optical design delivers equal radiance over the entire field, for users desiring flat fielding fisheye or ultra-wide FOV
Johns, Chief Innovator at Digital FOV
said, "It depends on the environment you are hunting in.
Magnification affects FOV
, but so do ocular lens diameter and optimal eye relief.
In other words, Microsoft found a way to either keep the FOV
the same while shrinking the device or expand the FOV
while keeping the device the same size.
Figures 1 and 2 illustrate these FoV
and VID differences between traditional (past and present) HUDs and AR (future) HUDs.
Then, either the detector location rotates around the FOV
with the sample remaining fixed, or the detector remains fixed, and the sample rotates in the horizontal plane.
The CBCT system obtains images of the phantoms by changing FOV
, scan time, milliampere setting, and voxel size every time.
Pre-contrast technical parameters were TR:400, TE: 8.6, FOV
: 256X320, FoV
phase: 100, thickness: 3 mm, nex: 1 for T1; TR:3820, TE: 96, FOV
: 256X320, FoV
phase: 100, thickness: 3 mm, nex: 2 for T2; and TR: 1000, TE: 266, FOV
: 180X230, FoV
phase: 80, thickness: 0.7 mm, nex: 1.4 for 3D Turbo spin echo T2 (t2 spc-tra-p2 iso-0.6), TR: 5.6 ms, TE: 2.49 ms, FOV
: 235 mm, FoV
phase: 81.3, thickness: 0.7 mm, nex: 1 for T2- CISS 3d axial.
And it should be also noted that the purpose of the previous method was to enhance MTF at the isocenter, not to make MTF uniform across the FOV
. The proposed method is an extended method of the previous method  in that it does not require PSF measurement in every subband and can be applied to alleviate the problem of spatial variation of reconstructed image resolution in CT.
The seeker's field-of-view (FOV
) is a critical limit for missile engagement, especially when the missile utilizes a seeker with narrow FOV
and intercepts a high-speed target with terminal angle constraints [2, 3].
Usually autonomous guidance of star sensors with small FOV
is restricted by insufficient guidance star quantity.
One of the limitations in this study was the small field of view (FOV
), as the study was done using first generation dual-source DECT scanner.
