Errors in non-contact sensor measurements due to misalignment and scanning methodology

[Proceeding] A Fiber Optical Sensor For Non-Contact Vibration Measurements

A Fiber Optical Sensor For Non–Contact Vibration Measurements

Vibration tests are widely employed in many industrial fields, and in particular in aerospace industry to evaluate the mechanical behavior of parts for aircrafts and satellites. Usually, these tests are carried out with shakers, while inertial accelerometers are used to measure the shaker table acceleration from which the vibration amplitude is computed. Some applications require the measuremen...

3d Non-contact Measurements

Measurements are obligatory steps in every production process. Quality of products is closely related to the measurements and these links are given in the cycle of quality assurance. Inspection and measurements of products are carried out in all phases of product development. Control and measurements are undivided part of production in automatized and mass production. Every type of production c...

Estimation of discretization errors in contact pressure measurements.

Contact pressure measurements in total knee replacements are often made using a discrete sensor such as the Tekscan K-Scan sensor. However, no method currently exists for predicting the magnitude of sensor discretization errors in contact force, peak pressure, average pressure, and contact area, making it difficult to evaluate the accuracy of such measurements. This study identifies a non-dimen...
