However, the largest potential uncertainty of
autocollimator measurements arises from optical aberrations in imaging non-flat artifacts.
Hardly a dimenewcomer to machine-tool calibration, the
autocollimator was created for this use in the '40s, replacing cumbersome master straight edges, squares, and flats.
Thus with the help of one polygon and one
autocollimator it is possible at a certain pitch (depending on the number of polygon edges) to determine edge values of the tested device (test rig in our case) within a full circle.
Using an
autocollimator and a reference prism, this angle was measured with a statistical standard uncertainty of better than 1" and a combined standard uncertainty of [+ or -] 9".
The reference measure used for the calibration of vertical angle measurement accuracy for machine engineering and geodetic instruments is based mainly on the use of multiangle prism--polygon [4, 7] or precision rotary encoder connected to the axis of the test bench and equipped with an
autocollimator placed in front of the axis of optical tube of the instrument.

The
autocollimator 6 is placed on a stationary part of test rig and pointed to the mirror.
To ensure high reliability, they should be calibrated using standard instruments such as an indexing table along with an
autocollimator (Just et al.
An optical device called an
autocollimator is used to analyze the pitch and yaw.
An
autocollimator is used to transfer the level to a small, flat mirror probe on a leveling assembly.
During the fourth quarter, the company released the Laser Distance Sensor (LDS) electronic
autocollimator for non-contact measurement and alignment tasks in laboratory and industrial settings.
