    摘要: An optical feedback technique is utilized for accurately determining the angular orientation of a collimator relative to an electro-optical (EO) system, and for aligning the two. A mirror assembly mounted on the EO system comprises a plurality of mirror elements positioned to receive light from the exit aperture of the collimator and to reflect the light back into the collimator through the aperture, each of the mirror elements having a reflecting surface oriented at a predetermined, unique angle. A beam of light reflected from one of the plurality of mirror elements forms a light spot on a photosensitive surface at the focal plane of the collimator. The relative orientation of the collimator and the EO system is determined by comparing the position of the light spot on the photosensitive surface with a reference position. An error signal is generated based on the comparison of the position of the light spot with the reference position, and in response to the error signal, the orientation of the collimator is adjusted relative to the EO system to align the optical axes thereof.

    摘要: An in-line night-day boresight with an adjustable wedge-prism assembly is disclosed. The adjustable wedge-prism assembly includes two opposing wedge prisms that are axially rotatable relative to each other. The assembly is arranged in the optical path between the night optics and the day optics. The adjustable wedge-prism assembly allows for compensation of image shift errors introduced by the night optics due to manufacturing errors in the night optics. This in turn allows for a cost-effective and easily aligned in-line night-day boresight.

    摘要: An optical alignment system for controlling the position of a laser beam through an optical train. The optical alignment system includes a semiconductor laser source for the generation of an alignment beam, and a beam steering device to manipulate the position of the alignment beam on a multi-element detector. The semiconductor laser is driven to mode hop at a frequency greater than the upper frequency limit of the multi-element detector. Driving the semiconductor laser to mode hop at a frequency greater than the upper frequency limit of the multi-element detector results in a more uniform alignment beam as seen by the detector, as the alignment beam becomes an average of all the operational modes of the semiconductor laser. A more uniform alignment beam results in improved accuracy of the alignment system.

    摘要: An optical system has an extended boresight source including a boresight light source that produces a light beam, a condenser lens that receives the light beam from the boresight light source, a spatial light integrator that receives the light beam from the condenser and mixes the light beam to reduce its spatial inhomogeneities, a constriction through which the light beam from the spatial light integrator is directed, and a collimator that receives the light beam which passes through the constriction and outputs a boresight light beam. The boresight light beam is typically provided to a sensor imager that uses the boresight light beam to establish its centroid.

    摘要: This invention relates to laser guided weapon systems and in particular to boresighting a designator laser to a forward looking infrared (FLIR) sighting system that is at a wavelength other than that of the laser with sufficient accuracy, confirming adequate power level available for designation and that the proper pulse rate code has been selected and is being transmitted. Due to the nature of the designation laser being at a different bandwidth than the FLIR, the positioning of the laser spot is not visible to the targeting system and the initial system alignment is depended on for accuracy and precision. This invention presents a way of addressing three aspects of laser designation prior to weapon use. This is achieved through the use of a beamsplitter and thermal resistor that appear to be at the same point of space to the targeting system. The offsets are measured and then used to correct the misalignment.

    摘要: A FLIR boresight alignment system (52) for aligning a sensor pod LOS associated with a weapons pod of a fighter aircraft to a navigation reference frame. A pod inertial navigation and global positioning system (62) provides position, velocity and attitude of a sensor (58) within the pod. An aircraft inertial navigation and/or global positioning system (68) provides position, velocity and attitude of the aircraft. The sensor position and velocity and the aircraft position and velocity are applied to a transfer alignment filter (64) that utilizes Kalman filtering. An output of the transfer alignment filter (64) is applied to a sensor inertial navigation system to correct the pod LOS relative to the navigation reference frame. Alternately, the transfer alignment filter (64) may operate directly upon the pseudo ranges and delta pseudo ranges to satellites being tracked by the GPS receiver.

    摘要: A fixture automatically aligns a laser transmitter bolted to a rifle. A case is horizontally oriented and a hinged end cover is swung upwardly to reveal a control unit. The barrel of the rifle is supported on a weapon rest mounted to the base unit and the trigger guard or clip receptacle is mounted in a vise on a sliding rack inside the case. The vise has knobs for adjusting the azimuth and elevation of the weapon, thereby permitting the soldier to aim at a target reticle. An optics unit is mounted on a forward portion of the base unit and includes a lens and a beam splitter which is transparent to infrared light from the laser transmitter but reflective to visible light. The illuminated target reticle is mounted inside the optics unit. The beam splitter is positioned forward of the lens and is angled at forty-five degrees to project the image of the target reticle through the lens at infinity. A position sensor detector receives the laser beam and generates an error signal representative of a displacement between a received location of the laser beam and the image of the target reticle. A circuit causes the alignment head to repetitively trigger the laser in the laser transmitter. Utilizing the error signal, the circuit causes the alignment head to independently rotate wedge prisms in the laser transmitter to steer the laser beam in azimuth and elevation until the laser beam is substantially aligned with a boresight of the weapon.
