  • Patent number: 8514382
    Abstract: A method and optical device measures the rotation of an object, including a light source emitting a collimated incident light beam, and a reflecting plane optical interface to be fastened to the object and forming a first reflected beam. The device includes a corner reflector fastened to the object, and having reflecting plane faces forming a second reflected beam, and a detection system capable of measuring the displacement ?1 of the first reflected beam, and the displacement ?2 of the second reflected beam. A processing system calculates, as a function of ?1 and of the distance D1 between the detection system and the reflecting plane optical interface, and of the measurement of ?2 and of the distance D2 between the detection system and the corner reflector, a measurement of the rotation ? of the object between an initial position and a measurement position.

  • Patent number: 8400625
    Abstract: Systems, devices, and methods are disclosed for testing the boresight of a gimbaled camera and laser system, such as an infrared countermeasures (IRCM) system, in extreme environments. Light simulating a target is reflected through an optics system to the camera, with a portion of the light reflected back from a corner cube reflector through the optics system as a reference. A laser beam from the laser is received through the same optics system, and a position of the corner cube reflected reference and laser beam are compared in order to determine whether the camera and laser are properly aligned. A spherical shell adapted to position the camera at its geometric center keeps misaligned laser pulses from reflecting back into the camera.

  • Patent number: 8378279
    Abstract: A portable integrated laser optical target tracker and designator (PILOTT device) in a single housing is provided having a laser designator assembly to produce a focused laser beam that is projected from the housing. A laser energy detector is located in the housing that detects reflected laser energy from any designation source (ground or airborne based), provides steering information, decodes the laser's frequency, and is used as a range finding receiver. The location of the laser energy provides automatic field alignment of the laser designator. An optical magnification scope is mounted in the housing and has an optical field of view that is parallel to and aligned with a beam path defined by the laser beam focusing optics. Any night scope can be added to the system to provide night situational awareness by being shown in the display. A visual electronic display is overlaid with the optical field of view.

  • Publication number: 20120300199
    Abstract: An optical analysis method is provided for judging whether a lens and a sensing element of an image pickup device are parallel with each other. The method utilizes a tested image pickup device and a standard image pickup device to shoot an object at the same fixed shooting position to acquire a standard image frame and a tested image frame. According to the difference between the position coordinate value or the area of at least one mark of the standard image frame and the tested image frame, the method can judge whether the tested lens and the tested sensing element of the tested image pickup device are parallel with each other.

  • Publication number: 20120171643
    Abstract: An alignment device is provided for a weapon that generates a simulation beam and an alignment beam that is used to properly align the simulation beam with the weapon's sight. The device can be secured to the weapon during the alignment process, after which it can be removed. The device includes a housing that can be mounted on the weapon so that its optical receiving port intersects both the optical alignment beam generated by the optical transmitter and the sighting axis of the weapon's sight. The optical receiving port includes an optical arrangement for receiving the alignment beam and focusing it on a projection screen located inside the housing. An image of the alignment beam on the projection screen can be viewed through the sight by a user. The alignment beam is parallel to the simulation beam. Thus, by centering the alignment beam in the sight, the alignment beam, and hence the simulation beam, will be properly aligned.
