Optical traps allowed these biophysicists to observe the forces and dynamics of nanoscale motors at the single-molecule level; optical trap force-spectroscopy has since led to greater understanding of the stochastic nature of these force-generating molecules. Optical tweezers have proven useful in other areas of biology as well.
If you see one mouse in your home, there are likely more you don’t. Get rid of them with the best mouse traps, whether you prefer to snap, zap, or catch and release.
The trapping of micrometre-sized particles by two laser beams was first demonstrated by Arthur Ashkin in 1970, [1] before he developed the single-beam trap now known as optical tweezers. An advantage of the single-beam design is that no two laser beams need to be exactly adjusted to make their optical axes match.
Optical mouse: Lyon was one of two people who independently invented the first optical mouse devices. [21] The other was Steve Kirsch, who independently invented a different type of optical mouse at MIT at approximately the same time. Both of them applied for patents on their schemes in mid-1981, and each of them received two U.S. patents (now ...
An active electronic motion detector contains an optical, microwave, or acoustic sensor, as well as a transmitter. However, a passive contains only a sensor and only senses a signature from the moving object via emission or reflection. Changes in the optical, microwave or acoustic field in the device's proximity are interpreted by the ...
