Objective assessment of structured surfaces that matches human perception<\/h3>\n

The standard quality control procedure for structured surfaces of the interior design of passenger aircrafts<\/strong> is a manual inspection of each surface, which is obviously a highly subjective process.<\/p>\n

Conventional systems for surface roughness measurements only provide data on standard roughness<\/strong> and typically only measure along a short straight line. Therefore, they are insufficient to correctly capture the visual appearance<\/strong> of such textured surfaces. With these methods, small variations of the surface coarseness that are visible to a human eye are difficult to convert into objective inspection results.[\/vc_column_text][vc_column_text css=”.vc_custom_1712564599184{margin-top: 50px !important;}”]<\/p>\n

Solution<\/h2>\n

The T-SCAN sensor provides a robust inspection solution by capturing a surface area which is sufficiently large (typical 50×50 mm) to obtain an accurate assessment of the surface properties<\/strong> (e.g. reflectance) relevant for human impression.<\/p>\n

The sensor captures a series of images using different illumination angles<\/strong> that are combined to obtain values of gloss and coarseness (perceived roughness) of the surface. In a first step, these values are used for a reproducible comparison between different surface textures and the definition of tolerance limits which reflect the visual appearance as perceived by a human quality expert.<\/strong> During measurement, the sensor is capturing the surface in 2D and the algorithm provides an accurate value for the surface properties.[\/vc_column_text][vc_column_text css=”.vc_custom_1712564615902{margin-top: 50px !important;}”]<\/p>\n
