Summary: The revised International System of Units (SI) introduced the use of a Kibble balance to measure ultrasonic power without the need for precise gravity acceleration measurements. A low-cost benchtop Kibble balance was developed with a 3D printer, Raspberry microcomputer, oscilloscope, and Python programming language. The prototype achieved satisfactory results in measuring radiation power within the range of 1.4 W to 21.7 W.

Summary: This study presents a method for evaluating the uncertainty of stress-optic coefficient measurements in photoelastic materials on a uniaxial tension/compression specimen. Unlike previous methods, this approach considers multiple data fitted with ordinary least squares, but only the repeatability contribution to uncertainty is considered, which is inconsistent with the ISO-Guide. The General Least Squares-Lagrange Multipliers (GLS-LM) method introduced here allows for the consideration of all possible contributions to uncertainty. An example illustrates that uncertainty has been underestimated in previous methods. In addition to estimating the stress-optic coefficient and its corresponding standard uncertainty, this method also provides a data consistency test and an outlier identification tool.

Summary: This work proposes an approach to investigate measurement uncertainty in coordinate metrology by fitting Gaussian random fields to high-density point clouds. The fitted field provides a spatial distribution of random measurement error over part geometry, and allows for Monte Carlo simulation to study error propagation through the data processing pipeline affecting feature determination and conformance verification. The approach is validated with simulated test cases and real part measurements, demonstrating its usefulness for estimating measurement uncertainty and evaluating measurement solutions in industrial part inspection.

Summary: This study investigates the deviations of distance measurements in high-end phase-based depth cameras and proposes a method to reduce these biases based on experimental data. The results show that the response to external temperature varies among cameras, but the distance biases are similar. The study also demonstrates the potential for batch error compensation.

Summary: The framework of Geometrical Product Specification defines nominal geometry and characteristic tolerances of components. ISO standards describe nine geometrical properties per characteristic of a workpiece. This paper introduces a digital twin of an optical measurement system as a holistic concept for uncertainty determination based on specific tasks. Different measurement strategies are applied to illustrate their effect on the uncertainty of size, distance, form, and orientation properties.

Summary: Fisher information is used to quantify the maximum precision of estimating parameters encoded in quantum states using general quantum measurements. However, it does not account for the robustness of quantum estimation schemes against measurement imperfections. This study introduces a new concept of Fisher information measurement noise susceptibility, which quantifies the potential loss of Fisher information due to small measurement disturbances. An explicit formula for this quantity is derived and its usefulness is demonstrated in analyzing quantum estimation schemes such as interferometry and superresolution optical imaging.

Summary: Precise dimensional measurements in manufacturing industries are largely influenced by coordinate metrology. An experimental investigation was conducted to verify an articulated arm coordinate measuring machine using a one-dimensional standard artefact. Monte Carlo Simulation method was used for uncertainty estimation and compared with ISO GUM outcomes, showing reasonable concordance.

Summary: This study presents a multi-target automatic positioning method based on rapid angle and distance measurement, which can precisely and efficiently measure the three-dimensional coordinates of large-scale components in the manufacturing process of aircraft and ships. By decoupling the measurement processes for angles and distances and introducing a cooperative target, the method aims to enhance the measurement efficiency and automation. The experimental results demonstrate that the 3D coordinate measurement accuracy of this method is better than 0.17 mm.
