  • Patent number: 10502949
    Abstract: A LIDAR system comprising a pyramidal timing polygon is having a plurality of flat optically reflective facet surfaces. The pyramidal polygon comprises a plurality of spaced apart apertures disposed about the outer circumference thereof to define the plurality of radially disposed facets. The pyramidal polygon is rigidly attached and aligned with the rotating scanning polygon structures to define a pre-defined angular shift. The rotation of the three polygon assemblies is synchronized with a pulsed laser source whereby, for each laser pulse, the individual pyramid facets are disposed at a predetermined angle, such as a 45 degree angle, with respect to the incoming beam so as to direct it along the beam 1 reflective optical path.

  • Patent number: 10185033
    Abstract: The ACASS 3D LIDAR system operates in a fundamentally new manner combining features of flash LIDARS and scanning LIDARS simultaneously which enables mission and performance trades to be conducted by varying the sizes of illumination patches within the scenes being observed. Further the combination of these modes of operation into a single LIDAR system enables multiple modes of operation and multiple missions to be accomplished with single lasers obviating the need for multiple lasers and enabling significant simplification of beam control modes. Systems which result from the new, expanded size, weight, power, cost trade space enabled by the ACASS concept can provide new levels of performance at significantly reduced risks and costs The achievement of wide area, three dimensional imaging using a LIDAR sensor system is accomplished with one laser which operates using an eye safe fiber laser with very high puke 13 rates but very low energy per pulse.

  • Patent number: 9810776
    Abstract: A mechanical scanning system for the illuminating laser beam and return light in LIDAR imaging systems. The scanning system includes a flat mirror having reciprocating rotary motion around a horizontal axis for vertical scan of the illuminating laser beam and return light. The reciprocating rotary motion of the mirror is driven by a continuously rotating motor, a cam mounted on the motor and a follower connected to the mirror and driven by the cam. An encoder is connected to the mirror's shaft and provides position indication to the imaging control electronics.

  • Publication number: 20170009933
    Abstract: A gimbal for airborne and moving platforms that uses a gyroscope as a rotational anchor for payload stabilization. Unlike current stabilized gimbals that sense rotations and correct by using motors, the proposed gimbal uses a passive approach that maintains the payload orientation instead of forcing it back after it rotated out of the desired orientation.

  • Publication number: 20150021454
    Abstract: An autonomous remote anchor system for providing an anchor connector to a surface, such as a ground anchor for an unattended ground sensor is disclosed. An inflatable positioning structure is inflated and configured to orient an anchor assembly in a vertical orientation with respect to the ground or surface upon which it is disposed. Upon vertical orientation, an actuator in the anchor assembly, such as a voice coil, is energized and drives a hammer element that is slideably disposed in the housing, striking the upper surface of the anchor. The drive cycle is repeated, driving it into the surface until the depth of penetration is sensed by a load sensing element.

  • Publication number: 20140300798
    Abstract: A multi-imager camera having a focusing means attached to each imager in the form of a Z actuator and having an image-splitting optical assembly that splits the scene's energy to the individual imagers while maintaining the full scene coverage and while having all imagers placed in the same back-focal-distance that matches that of the camera's lens. The above camera focuses the individual imagers to different parts of the scene by individually controlling the Z actuator of each imager, and captures all images instantaneously for real-time on-board image processing or for post processing.

  • Publication number: 20140259711
    Abstract: A device capable of measuring the vector sum of the centripetal acceleration of the rotation of the Earth (or that of any other planet in a planetary system) around its axis (a.sub.rot) and the centripetal acceleration of the planet's revolution in its orbit around the Sun (a.sub.rev) and a method for performing the same using the measured physical data to calculate the latitude and longitude of the device on a surface. Measurements are taken by stepping accelerometers through different axis to determine centripetal acceleration, reading the output of the accelerometers and reading the angular disposition of the accelerometers using encoders and calculating the latitude and longitude from the measured data.

  • Publication number: 20140240810
    Abstract: A drive apparatus and a beam-steering apparatus fabricated from a MEMS process. The apparatus has a first layer, a second layer and a plurality of fluid-filled volumes defined there between. A plurality of flexible structures such as bellows structures are defined on the first layer and are configured whereby a predetermined pressure in each of the volumes results in a predetermined displacement of the flexible structures. Pressurization means selectively changes the pressures in each of the volumes to define the predetermined displacement of the flexible structures. An electromagnetically reflective or mirror element and a plurality of drive beams are affixed to the reflective element and to one of the plurality of flexible structures whereby selected pressurization of the fluid in the volumes causes a predetermined displacement of the flexible structure to displace the reflective element about the plane of its surface.
