Because the stage is designed to be supported from the bottom of the microscope near the optical axis and incorporates steel cross roller guides, it is twice as stable and durable as conventional stages.
If the target is not detected directly through the optoelectronic system of the seeker, the optical axis of the head will be automatically set according to the programmed motion and, as a result, the scope of scanned space will be increased.
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.
The vertical centration should then be compensated for the pantoscopic tilt of the spectacle frame to ensure that the optical axis of the lens passes through the eye's centre of rotation.
When scopes became popular on bolt-action rifles, gunmakers began offering stocks with less drop--or with elevated/adjustable cheekpiec-es--to bring the shooter's eye up where it would naturally align with the optical axis of the scope.
The two foci used in the M5 test (visible through the alignment telescope) marked the mirror's optical axis and so M5 could be adjusted in tip/tilt and decentre, with feedback from the Faro, until it was lined up with the optical axis of M2.

The parts in this product are mounted flat on the system's XY stage and the optical axis is vertical (the lens is looking down on the components), according to the Canadian developer of software and systems for automated visual inspection and high-accuracy measurements.

In our setting "reconstruction" has the following meaning: The true density of the fluorophores in a xy-plane perpendicular to the optical axis and of distance z from the microscopic lense is estimated using the data of the set of CLSM-slices which are closer to the lense.
