Abstract:

This paper describes a method and a precision optical sensor for remotely determining the coordinates of the center of a spherical interaction chamber (the target chamber) 10 m in diameter to within ±20 μm when the target of a multichannel laser installation intended for studies in high-temperature plasma physics is being automatically adjusted.
