Summary: This paper presents an absolute phase unwrapping method for high-speed three-dimensional shape measurement on a single-camera, single-projector structured light system. The method utilizes speckle-embedded three-step phase-shifted patterns to obtain the wrapped phase of the object and employs the Semi-Global Matching (SGM) algorithm to establish the coarse correspondence between images. A computational framework is then used to determine the fringe order pixel by pixel. The experimental results demonstrate the high-speed and high-quality 3D measurements achieved by the proposed method for complex scenes.

Summary: V/LiF is an important window material for investigating phase transition of materials under ultra-high pressure, which is a fundamental issue in condensed matter physics. However, the large mismatch in lattice and thermal properties makes vanadium growth on LiF a big challenge. In this study, over 1.5 μm thick vanadium films were successfully grown on LiF using facing target sputtering (FTS), and transmission electron microscopy (TEM) observation revealed vertically well-aligned columnar crystals with numerous micro-sized gaps in the grown vanadium films. Particle-in-cell Monte Carlo collision (PIC-MCC) and Kinetic Monte Carlo (KMC) methods were used to simulate plasma discharge behavior, sputtered atom transport, and film growth to understand the deposition mechanism. A growth model of the vanadium film was established based on experimental and simulation results, and the micro-sized gaps in the columnar crystals were found to contribute to the release of residual stresses caused by the large mismatch, which can be explained by the grain boundary relaxation model.

Summary: Light beams possess three types of angular momentum, namely spin angular momentum, extrinsic orbital angular momentum, and intrinsic orbital angular momentum. The interaction between these momenta leads to the spin-orbit interaction of light and topological effects. This study predicts a new topological effect resulting from the influence of extrinsic orbital angular momentum on spin angular momentum in converging asymmetrical light beams. It manifests as the transformation of linear polarized light into elliptically polarized light when an asymmetrical beam passes through the left or right half of the focal plane. The measured value of the topological circular amplitude anisotropy R was found to be R = +/- (0.60 +/- 0.08) x 10(-3). This new effect contributes to our understanding of light and has potential applications in developing sensors in optics.

Summary: Due to the complexity of resolving object form and pose in images, new vision algorithms prioritize identification and perception over accurate coordinate measurement. However, the use of planar targets for coordinate measurement in vision systems has several drawbacks, including calibration difficulties and limited viewing angles. On the other hand, the use of sphere targets is infrequent in vision-based coordinate metrology due to the lack of efficient multi-view vision algorithms for accurate sphere measurements.
