  • Publication number: 20200292382
    Abstract: A single shot autocorrelator for measuring duration of an ultrashort laser pulse in the far field, having a beam splitter to form two beams from an input ultrashort pulse: the reflected beam is firstly reflected by two mirrors mounted on a translation stage for adjusting time delay and subsequently a third mirror, and after focused by a spherical convex lens, enters a naturally grown strontium barium niobate crystal along the crystal z axis; the transmitted beam is firstly focused by a spherical convex lens, and after reflected by two mirrors, enters the crystal along the crystal z axis from opposite direction. The crystal is in the common focal regions of two spherical convex lenses and generates the transverse second harmonic pulse beam that is the autocorrelation signal to be recorded, which is imaged with an optical microscope onto a charge coupled device camera mounted perpendicular to the beams.

  • Patent number: 10341413
    Abstract: Provided are a method and system for synchronizing a robot with a server. The service sends a time service command including a current time of the server to the robot, and the robot receives the time service command, so as to enable time synchronization of the robot with the server. A control device receives first command data carrying a first timestamp sent from the server, and then determines whether the first timestamp in the first command data has expired. If the first timestamp has expired, the control device receives command data resent from the server until second command data carrying an unexpired second timestamp is received. Finally, the control device controls the robot to execute a corresponding action at a time corresponding to the second timestamp based on the second command data, so as to realize the synchronization of the robot with the command data sent from the server.
