摘要： A day/night sight includes a visible-light first optical path and an invisible-light second optical path which are everywhere optically coaxial. The invisible-light second optical path leads to a detector or to an image intensifier tube for providing either an electrical signal or a visible image, respectively, in response to the invisible-light image. A third optical path for the visible image from the image intensifier tube is also everywhere optically coaxial with the first and second optical paths. A visible image produced from the electrical signal is introduced into the first optical path to thereafter be coaxial therewith. Consequently, a uniquely compact arrangement of the elements for the day/night sight is achieved.

摘要： An anode structure of the present invention provides radially disposed first vanes and radially disposed second vanes interdigitating with the first vanes. The first vanes and the second vanes are each interconnected by a first strap and a second strap, respectively. The first strap and the second strap are disposed coaxially on the same side of the vane structure and are generally rectangular in cross-section, having substantially parallel facing surfaces. Each of the vanes is generally T-shaped, with a relatively wide high capacitive first portion and a relatively narrow high inductive second portion. The first portion is disposed proximate to an axis of the cavity with the second portion extending radially outward therefrom. The anode structure has at least thirty anode vanes.

摘要： A leaky wall filter for use in an EIK comprises a plurality of guidelets intersecting perpendicularly with a wall of an output waveguide of the EIK. The guidelets would propagate 2.pi. mode oscillation frequencies from the EIK out of the output waveguide. A load matched to the 2.pi. mode disposed at the end of the guidelets provides termination for the 2.pi. mode oscillation frequencies and prevents the initiation of oscillation. The load comprises a plenum disposed at an end of the guidelets opposite to the output waveguide, a window having a first surface within the plenum, and a water load provided at a second surface of the window. The 2.pi. mode oscillation frequencies propagating through the guidelets are impedance matched by the window and coupled into the water load for termination. Since a portion of the operating frequency power also leaks through the guidelets into the plenum due to insertion loss, this combined RF power also couples into the water load and is converted into thermal energy. A fluid circulation system is provided to remove the thermal energy from the water load. The window is comprised of alumina ceramic which effectively couples the 2.pi. mode oscillation frequencies and RF power into the water load.

摘要： An extended interaction output circuit is provided for interacting with a modulated electron beam and for outputting RF electromagnetic energy. The circuit comprises a plurality of linearly disposed cavities having an axially extending beam tunnel to permit the traveling therethrough of the modulated electron beam as well as to couple electromagnetic energy between the successive cavities. Each of the cavities is separated by an annular disk having a hole providing the axial beam tunnel. The hole diameters increase in steps so that the impedance of the successive cavities decreases along the axial extent of the circuit. The diameter of the successive cavities is also increased as the associated width is decreased to maintain the same mid-band resonant frequency. The linearly disposed cavities act as an RF filter having successively tapered impedances to reduce reflections of the electromagnetic energy propagating through the circuit. The gap-to-gap distance between successive cavities is selected to provide a 90 degree phase shift of the beam in order to maintain synchronous operation between the beam and the wave at the mid band frequency.

摘要： A diode laser apparatus is heated at its junction by operating the diode at subthreshold current levels. A special bi-level pulse forming network (PFN) improves the efficiency in preheating the diode during non-operating or non-light producing modes along with the ability to supply the necessary drive during operating or light producing modes. This is accomplished by operating the laser diode at subthreshold or non-light producing current levels, which heats the diode at the diode junction directly where the heat is needed, and by the use of a bi-level pulse forming network which transfers the heating energy to the diode junction with high efficiency.

摘要： A magnetron transition apparatus is provided which permits transmission of a microwave RF signal between a magnetron and an output waveguide. The transition apparatus is connected to the magnetron and receives the RF signal from the magnetron, while maintaining a substantially vacuum environment therein. The transition apparatus further comprises an RF interface between the substantially vacuum environment and a non-vacuum environment within the output waveguide. The microwave RF signal from the magnetron is transmitted through the transition apparatus into the output waveguide. The transition structure comprises an adapter having a first portion of generally circular cross-section and a second portion of generally rectangular cross-section. A conductive loop electrically connected to an anode structure of the magnetron is disposed within the first portion and inductively couples the RF signal from the magnetron into the transition apparatus. The RF interface further comprises an RF transparent window connected between the second portion of the adapter and the output waveguide. The second portion of the adapter has a cross-section consistent with that of the output waveguide.

摘要： An interferometer amplitude modulation reduction circuit coupled to receive an interferometer output signal from the output of a fiber optic interferometer sensor. The interferometer sensor is excited by a frequency modulated input light signal from a light source having an unwanted amplitude modulation and intensity noise signal component. The interferometer output signal has both wanted interference induced intensity modulation and also unwanted amplitude modulation and intensity noise from the unwanted amplitude modulation and intensity noise signal components present on the frequency modulated input light signal. The invention circuit has a sampling means for sampling a sample portion of the frequency modulated input light signal from the output of the light source. The sampling means detects and the sample portion signal to provide a detected sample intensity signal having a detected unwanted amplitude modulation and intensity noise signal component. A detector detects the interferometer output signal from the output of the fiber optic interferometer sensor and converts the interferometer output signal into a detected AM modulated phase-generated carrier signal containing a detected unwanted amplitude modulation and intensity noise signal component. A divider scales and divides the detected AM modulated phase-generated carrier signal by the detected sample intensity signal to provide a corrected interferometer output signal. The detected unwanted amplitude modulation and intensity noise signal components common to both the detected sample intensity signal and the detected AM modulated phase-generated carrier signal are substantially canceled by the division process.
