Replay: About a year ago, we covered the ISO and ASA systems as they apply differently to film and video cameras. There's been a lot of interest in that article, especially when it was republished ...
ABSTRACT.Curvature wavefront sensors measure wavefront phase aberration by acquiring two intensity images on either side of the pupil plane. Low-order adaptive optics (AO) systems using curvature ...
Twist, bend and stretch The new stretchable sensor can detect even minor changes in strain with greater range of motion than previous technologies. The patterned cuts enable large deformation without ...
(Nanowerk News) Wearable, flexible strain sensors unobtrusively monitor tiny vibrations of human skin in real time and with great accuracy, thanks to innovative fabrication techniques using composite ...
