Principles for the Construction of a Metrological Complex for Certification of High-Precision Optoelectronic Goniometers

Abstract

The geometric diagram of a bench for determining the instrument errors of high-precision two-dimensional optoelectronic goniometers is considered. These errors are found by measuring the angles between known spatially fixed reference directions and comparing the values obtained to the sizes of these angles measured by means of autocollimators oriented to a special caliber (calibrating prism) that fixes the point of intersection of the geometric axes of the controlled goniometer. The caliber standard is in the form of a multifaceted prism with reflective surfaces the normals to which form the required geometric diagram in space.
