  • Optical monitoring of scan parameters
    Patent number: 10012831
    Abstract: Scanning apparatus includes a transmitter, which is configured to emit a beam comprising pulses of light, and a scanner, which is configured to scan the beam along a scan axis over a specified angular range. A scattering line extends across a path of the scanned beam. A receiver is configured to receive the light scattered from the scattering line and to generate an output indicative of an intensity of the scattered light. A controller is coupled to process the output of the receiver so as to monitor operation of the scanner.
    Type: Grant

  • Delay diversity in antenna arrays
    Patent number: 7970359
    Abstract: In a wireless transmission system including a transmit delay module, delaying each of at least one copy of a signal by a respective delay, the signal being transmitted over a plurality of carrier frequencies and over at least one beam, the at least one beam exhibiting a beam pattern, the number of copies of the signal corresponding to the number of beams, each the at least one copy being associated with a respective one of the at least one beam, the system further including a beam pattern former, coupled with the transmit delay module, producing a plurality of transmit signals corresponding to the beam pattern, a frequency dependent beam shifter, coupled with the beam pattern former, delaying each of the at least one transmit signal by a respective angular shift delay, thereby applying an angular shift to each of the at least one beam, the angular shift of each of the at least one beam corresponding to at least a respective one of the carrier frequencies, wherein each beam is transmitted with a delay correspo
