Levitated nanoparticles are promising tools for sensing ultra-weak forces of biological, chemical or mechanical origin and even for testing the foundations of quantum physics. However, such ...

Laser light is injected into an optical cavity to continuously measure the position of a movable mirror. The output light is read out by homodyne detection, and the measurement data are analyzed using ...

A tip-tilt-piston 3 × 3 electrothermal micromirror array (MMA) integrated with temperature field-based position sensors is designed and fabricated in this work. The size of the individual octagonal ...

Researchers at the University of Technology Sydney (Australia) have demonstrated the self-interference of fluorescent nanoparticles when placed on top of a mirror, altering images as each nanoparticle ...
