image plane

[′im·ij ‚plān]
(optics)
The plane in which an image produced by an optical system is formed; if the object plane is perpendicular to the optical axis, the image plane will ordinarily also be perpendicular to the axis.

1997) showed that surface diffusion was most severe when the object was located at the centre of an image plane.
New imaging sensor is also expected on Sony Xperia Z4 after Sony announced the Exmor RS IMX230 that features an Image Plane Phase Detection Signal Processing Function for high-speed autofocus.
This is the industry's first CMOS image sensor for smartphones to be equipped with an onboard image plane phase detection AF signal processing function to achieve excellent focus tracking of fast-moving subjects.

To then obtain the image of point (x',y' = 0) the new wavefronts are propagated to the appropriate image plane of the lens and the complex amplitude of that point recorded.
Skew distortion, perspective distortion, scale distortion and other geometric distortions, those distortions are caused by the relative rotation angle between the optical axis and the bar code plane, the relative angle and the difference between the distance and bar code image plane bending and other factors.
25 dg and perpendicularity of image plane to zenith direction is within 0.
The focusing mechanisms of SCTs could typically only move the primary mirror through a total distance of around 20mm, which was plentiful in the SCT configuration as the secondary mirror acted as a diverging lens, extending the focal length of the telescope by a factor of around five so that the eventual image plane could be shifted back and forth by as much as 100mm.
Therefore, it must be back propagated numerically to the image plane of the object to recover the object phase information.
Unlike the gratings and lenses approach in which the phase between the traps is fixed, this algorithm provides phase freedom by iteratively optimizing both, the hologram and the image plane phase values.
However, if we record the particles in the image plane of the lens we will observe (with a sufficiently high numerical aperture) two sharp spots 1' and 2' images of the pinholes 1 and 2.
Measurements in the axial scan plane are more convenient and rapid as this is the routine image plane provided; i.
