Advanced technologies for the calibration of machine tools are presented. Kinematic errors
independently of their causes are classified into errors within one-axis as intra-axis errors …

Beam splitters are widely used in various optical systems, but traditional beam splitters are
bulky and heavy, which are not conducive to the integrated utilization of optical devices …

Fano resonance with high Q-factor can greatly enhance the light–matter interaction in all-
dielectric metasurface, which is an important condition for developing high-performance …

At present, many refractive index sensors based on plasmonic structures are inefficiency in
practical applications due to the presence of metal ohmic losses. Here we propose an all …

This paper presents a robust and low-cost roll angle measurement system (RAMS) on the
basis of two parallel beams in association with two position detectors. The commonly …

The potential for enhancing the optical activity of natural chiral media using engineered
nanophotonic components has been central in the quest toward developing next-generation …

In 1822 A. Fresnel described an experiment to separate a beam of light into its right-and left-
circular polarization components using chiral interfaces. Fresnel's experiment combined …

The capacitive angle sensor has good output linearity, high precision and good dynamic
response. The designed sensor probe has a differential multilayer ring structure, which …

Remote measurement of object orientation is often required in many applications. Out of the
six degrees of freedom (DoF) that determine object orientation in space, the roll angle is the …

Dual-parameter measurements of refractive index and methane concentration based on
electromagnetic Fano resonance are proposed. Two independent Fano resonances can be …
