Ym. Golubovskii et Ln. Pivovarova, MEASUREMENT ERROR OF A PHOTOELECTRIC AUTOCOLLIMATOR AT DIFFERENT DISTANCES TO THE AUTOCOLLIMATION MIRROR, Journal of optical technology, 62(6), 1995, pp. 410-412
When the plane of the mark (the reticle) does not coincide with the fo
cal plane of an autocollimator objective, a component of the measureme
nt error appears that depends upon the distance to the autocollimation
mirror. A formula has been derived and analyzed that characterizes th
is error. A recommendation is given relating to the setting of the pla
ne in which the image position of the autocollimation mark must be mea
sured to attain the lowest error for different distances to the mirror
. Experimental data for the adjustment of a photoelectric autocollimat
or confirm that the theoretical considerations are correct.
