Robust high-precision 2D optical range sensor

Optical sensors exhibit a number of properties that make them interesting for a variety of applications in measurement science. The main contribution of this work is the development and the experimental validation of a 2D optical range sensor used in a quality control application. While various solutions for distance measurement in 2D exist, the proposed sensor and its associated signal processing algorithms are able to greatly simplify the sensor calibration and its on-site adjustment. The sensor design is motivated by the specific needs of quality control measurements on large cylindrical structures. Experimental results indicate the accuracy of the sensor and its applicability to quality control measurements.
