This article describes an innovative interferometric system for the inspection and quality control of glass slabs. The instrument exploits a self-mixing superluminescent diode scheme to improve the interferometric signal and to reject typical noise and electromagnetic interference existing in industrial environments. Various instrumental aspects and performance issues are discussed. Experimental activities demonstrate a system measuring range of 4.5 mm with a relative measurement uncertainty of less than 2%. Whereas, the measuring stability was measured to be about 2.5 mum over 20 min.

Abstract

This article describes an innovative interferometric system for the inspection and quality control of glass slabs. The instrument exploits a self-mixing superluminescent diode scheme to improve the interferometric signal and to reject typical noise and electromagnetic interference existing in industrial environments. Various instrumental aspects and performance issues are discussed. Experimental activities demonstrate a system measuring range of 4.5 mm with a relative measurement uncertainty of less than 2%. Whereas, the measuring stability was measured to be about 2.5 mum over 20 min.
