An optical system can include a mirror that reflects incoming light to a sensor for detection. The position and/or orientation of the mirror can be controlled to reflect incoming light from different locations and/or directions. Position and/or orientation of the mirror may be tracked and/or detected by an optical position sensor. The position sensor can transmit a beam to a reflector on the mirror, and the reflected beam can be received by the position sensor. Characteristics of the reflected beam can be measured to determine the position and/or orientation of the mirror. For example, the beam can be used for interferometric and/or intensity measurements, which can then be correlated with a position and/or orientation of the mirror.

A boresighting mechanism for adjusting an armament of an aircraft. The mechanism includes a housing comprising a proximal end, a distal end, and an inner cavity. The mechanism further includes a jackscrew with a threaded portion disposed in the inner cavity and an unthreaded portion extending from the proximal end of the housing. The mechanism further includes a follower threadedly coupled to the jackscrew at a first end within the inner cavity and extending from the distal end of the housing. The follower is configured to be coupled to an adjustment feature of the armament at a second end. The mechanism further includes an adjustment knob coupled to the unthreaded portion of the jackscrew and configured to rotate the jackscrew to thereby cause linear motion of the follower. The linear motion allows for adjustment of the armament via the adjustment feature.

An aircraft includes a main body having an empennage, a main rotor assembly mounted on the main body, and a movable control surface assembly supported on the empennage. The movable control surface assembly includes a tube extending from the empennage along a tube axis to a free end, the tube being supported for rotation about the tube axis with respect to the empennage, and a movable control surface mounted on the tube for rotation therewith. The movable control surface is supported on the tube by a connection element that couples the movable control surface to the free end of the tube to rotatably fix the movable control surface with respect to the tube.
A feed network is provided that includes a transmit section, a body section coupled to the transmit section, and a receive section coupled to the body section. The transmit section and the body section form a transmitter unit coupled to a first section of a core waveguide, wherein the first section of the core waveguide is a square waveguide. The body section and the receive section form a receiver unit coupled to a second section of the core waveguide, wherein the second section of the core waveguide is a circular waveguide.
