TL;DR: A new highly compact interferometer to allow for traceability and an uncertainty in the Angstrom range was developed and one of its first applications will be the new metrological low-noise atomic force microscope at the Physikalisch-Technische Bundesanstalt.

TL;DR: In this paper, a modified homodyne Twyman-green interferometer is proposed for 6° of freedom (DoF) measurement with Angstrom resolution for displacement and μrad resolution for angle measurement, respectively.

TL;DR: An optical imaging module design for an astigmatic detection system (ADS) based on a commercial optical pickup unit (OPU) and it contains a coaxial illuminant for illuminating a specimen that has the potential to be used in high-speed atomic force microscopy.

TL;DR: In this paper, a multi-point parallel large-range confocal microscope was designed and developed based on a digital micromirror device (DMD). Operated with specific patterns, the DMD can transform a single light source into multiple beams.

TL;DR: In this paper, a novel grating interferometer containing a commercially available, minimized Michelson interferometers and three fibre-fed measurement heads is presented for simultaneous displacement measurements in two perpendicular planes, where beam splitters are located in the fibre heads, therefore the grating is separated from the light source and the photo detector, which influence measurement results by generated heat.
