Nonmisadjustable optical systems of goniometers with a fixed line of sight

摘要

This paper discusses the optical systems of static goniometers equipped with a geometrical reference channel. Based on the concept of bringing the collimator and the mirror-prism system into coincidence as a single monoblock in the geometrical reference channel, a number of nonmisadjustable optical systems of goniometers with a fixed line of sight have been created. The best of these systems is one with an uncemented geometrical reference channel, made in the form of a new prism with three collimator-obscuras.
