Absolute Length Changes by Remote Interferometry.
Abstract
The subject of remote or 'contactless' length change measurements is reviewed. The development of a Michelson-type laser interferometer is described. Fringe analysis and system requirements to achieve continuous real-time delta l/l versus temperature curves with a resolution of less then 10 A are outlined. (Author)
