The paper presents the results of the development of an onboard
two-stage telescope monitoring (control) system of the Millimetron
space observatory. A 3D laser scanner is used for the preliminary
inspection of the reflector elements, and an image analyzer based on
the Foucault knife method is used for the final one. The results of
the calculation and modeling of the monitoring system
for tuning the telescope elements into space are presented. The
signals formed in the system are calculated, including using data on
the actual shape of the manufactured mirror elements. Estimates of the
expected measurement accuracy are given, and the test results of the
developed system are presented.
A contactless shadow method for measurements of the geometrical parameters of bullets and cases of weapon, its advantages and relevance are described. The results of beating measurements by an optical testing system are presented. It is shown that the shadow method has adequate accuracy for rejection of products according to permissible values for the nasal part beat, provides high performance productivity and allows to carry out rather fast calibration and readjustment of a system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
