Boston Micromachines 140-actuator poke test: reconstructed surface

Boston Micromachines 140-actuator poke test: reconstructed surface

This video shows the surface computed from the raw interferograms. The resulting height is in radians of phase at the interferometer’s laser’s wavelength of 633 nm. The purpose of the poke test is to determine the amount of deformation in the surface for a given applied actuator voltage. The actuator displacement force is electrostatic and [...]

Photonic MEMS: Vibration at the nano-scale (a)

Photonic MEMS: Vibration at the nano-scale (a)

Here we see how an electrical field applied by light can compress material to excite mechanical vibration. We replace metal electrodes with the electrical field that light applies to create a train of virtual electrodes that are almost exactly 250 nm apart. These virtual electrodes act collectivity to excite a mechanical mode, illustrated above, that [...]

Magic Mirrors Projecting 3D Illusions : DigInfo

DigInfo – http://movie.diginfo.tv Crystal Optics has expanded the application range of its crystal grinding technology to include precision grinding of various optical transmission materials such as metals and ceramics. At the 2008 Nanotech exhibition, Crystal Optics exhibited technology that produces clear, vivid, 3-dimensional optical illusions, using this crystal grinding technology. The illusion works by using [...]
