Abstract
A novel sensor array for metal-surface curvature and roughness inspections is investigated. The sensor is based on the use of a computer-generated hologram as an analyser of surface curvature and roughness. The sensor can be exploited to estimate the optical surface roughness of irregularly curved surfaces. A contrast parameter to characterize the optical surface roughness is introduced.
