Abstract

The research is based on a shift control system built on autoreflection scheme. The aim is to examine the possibility of using of the cat's eye reflector for the autocollimating alignment telescopes instead of more common tetrahedral reflectors (e.g. corner cube prism). Zemax simulations were made to study the influence of beam and image deformation (caused by this reflector) on the total system error. It is concluded that systems with large linear measurement range should have more exacting requirements of the mirror linear position adjustment while ones with small range require an accurate mirror tilt control. The alignment requirements for the cat's eye reflector were also estimated.
