- W2733013313 abstract "Surface micro topography measurement (e.g., form, waviness, roughness) is a precondition to assess the surface qualityof technical components with regard to their applications. Well defined, standardized measuring devices measure andspecify geometrical surface textures only under laboratory conditions. Laser speckle-based roughness measurement is aparametric optical scattered light measuring technique that overcomes this confinement. Field of view dimensions ofsome square millimeters and measuring frequencies in the kHz domain enable in-process roughness characterization ofeven moving part surfaces. However, camera exposure times of microseconds or less and a high detector pixel densitymean less light energy per pixel due to the limited laser power. This affects the achievable measurement uncertaintyaccording to the Heisenberg uncertainty principle. The influence of fundamental, inevitable noise sources such as thelaser shot noise and the detector noise is not quantified yet. Therefore, the uncertainty for speckle roughnessmeasurements is analytically estimated. The result confirms the expected inverse proportionality of the measurementuncertainty to the square root of the illuminating light power and the direct proportionality to the detector readout noise,quantization noise and dark current noise, respectively. For the first time it is possible to quantify the achievablemeasurement uncertainty u (Sa) < 1 nm for the scattered light measuring system. The low uncertainty offers idealpreconditions for in-process roughness measurements in an industrial environment with an aspired resolution of 1 nm." @default.
