Patent number: 11643194Abstract: A blade positioning system and method are provided to dynamically measure blade position during flight of a rotorcraft. In the context of a method, a blade of the rotorcraft is repeatedly illuminated by a light source during flight of the rotorcraft while the blade is rotating. The method also includes detecting radiation scattered from the blade in response to illumination of the blade. The method further includes determining at least one of a blade pitch angle, a blade flap angle, a blade leading position or a blade lagging position based upon the radiation that is scattered from the blade and detected. A rotorcraft is also provided that includes a chip-scale light detection and ranging (LIDAR) sensor configured to illuminate the plurality of blades while the blades are rotating in order to permit blade position to be measured or to illuminate terrain beneath the rotorcraft in order to provide an altitude measurement.Type: GrantFiled: December 17, 2019Date of Patent: May 9, 2023Assignee: THE BOEING COMPANYInventors: Keyvan Sayyah, Pamela R.

Patent number: 11573297Abstract: A vehicle, Lidar system and method of detecting an object is disclosed. The Lidar system includes a photonic chip having an aperture, one or more photodetectors and a circulator. A transmitted light beam generated within the photonic chip exits the photonic chip via the aperture and a reflected light beam enters the photonic chip via the aperture, the reflected light beam being a reflection of the transmitted light beam from the object. The one or more photodetectors measure the parameter of the object from at least the reflected light beam. The circulator integrated into the photonic chip directs the transmitted light beam toward the aperture and directs the reflected light beam from the aperture to the one or more photodetectors.
