Roughness measurement of metals using a modified binary speckle image and adaptive optics

Publication year: 2011 Source: Optics and Lasers in Engineering, Available online 6 December 2011 Yiin-Kuen Fuh, Kuo Chan Hsu, Jia Ren Fan This paper proposes an integrated roughness measurement system that is based on adaptive optics (AO) and binary analysis of speckle pattern images. The aim of this study was to demonstrate the necessity for AO compensation in regions containing both heat and fluid flow turbulences.
