  • Patent number: 7173711
    Abstract: Apparatus for and a method of rotating microscopic objects uses a beam of electromagnetic radiation. A microscopic, non-circularly symmetric distribution of electro-magnetic radiation is projected on to a region containing an object to be rotated so as to cause photons in the beam to refract around the objects. Rotating means then rotate that distribution and so rotate the objects. The distribution may be formed on the interference pattern between a beam having a Laguerre-Gaussian wave fronts and either a plane wave or a further Laguerre-Gaussian beam of opposite helicity.

  • Publication number: 20060103732
    Abstract: A method for fingerprinting a video involving identifying motion within the video and using a measure of the identified motion as a fingerprint. Once videos are fingerprinted, these fingerprints can be used in a method for identifying video. This involves creating a motion fingerprint for unidentified videos; comparing the fingerprints of the known and unknown videos, and identifying whether the unknown video is a copy of the known video based on the step of comparing.

  • Patent number: 6195167
    Abstract: There is provided an autocorrelator of ultrashort electromagnetic pulses, comprising an interferometer for receiving a parent electromagnetic pulse from an energy source and for deriving two daughter electromagnetic pulses from the parent pulse, an output means coupled to the interferometer to output the daughter pulses, and a photodiode in communication with the output means to detect the daughter pulses and to alter the frequency thereof so as to produce an electrical output signal that has a quadratic dependence on the power associated with the parent electromagnetic pulse. The temporal duration of the pulses ranges from TO picoseconds to 5 femtoseconds. A GaAsP photodiode is used with a broad band response of 700-1300 nm. The interferometer is either a Michelson interferometer or a Wollaston prism interferometer and a microscope objective is provided between the output means and the photodiode so that the pulses from the output means are focused onto a defined area of the photodiode.
