  • Patent number: 7872741
    Abstract: A method and an apparatus are disclosed for scatterfield microscopical measurement. The method integrates a scatterometer and a bright-field microscope for enabling the measurement precision to be better than the optical diffraction limit. With the aforesaid method and apparatus, a detection beam is generated by performing a process on a uniform light using an LCoS (liquid crystal on silicon) or a DMD (digital micro-mirror device) which is to directed to image on the back focal plane of an object to be measured, and then scattered beams resulting from the detection beam on the object's surface are focused on a plane to form an optical signal which is to be detected by an array-type detection device. The detection beam can be oriented by the modulation device to illuminate on the object at a number of different angles, by which zero order or higher order diffraction intensities at different positions of the plane at different incident angles can be collected.

  • Publication number: 20100226265
    Abstract: A method of Concurrent Multipath Transfer which is based on the relational paths, characterized in that for a packet lost in a path, it allows other packets sent from the path and/or other paths to point out the lost packet through a gap report. According to the present invention, any lost packets and abnormal paths can be found as fast as possible, and can be retransmitted quickly. So this method can avoid the failure of all paths from handing in packets to upper layer only for the abnormity in one path, which limits the speed of whole association.
