Methods and apparatus for a near-field signal system to generate signals underwater for navigation and/or communication. In one embodiment, a system includes a signal processing module coupled to a first antenna to transmit near-field signals underwater and a second antenna to receive near-field signals underwater transmitted by the first antenna. In one embodiment, a wetsuit includes an integrated near-field signal system.

An optical position sensing system and method for sensing a gimbal position in a gimbal-based optical system. One example of an optical position sensing system includes an off-gimbal light source that generates a position sensing light beam and transmits the position sensing light beam along an optical coude path of the optical system, and an on-gimbal optical element that causes a change in an intensity of the position sensing light beam based on rotation of the gimbal about the axis. The system further includes an off-gimbal detector configured to receive the position sensing light beam returned from the optical element and to detect the change in the intensity of the position sensing light beam, and a controller coupled to the detector and configured to determine the gimbal position based on a correlation between the change in the intensity of the position sensing light beam and the gimbal position.

Embodiments of a multi-mode seeker are provided for use in conjunction with a predetermined laser designator. In one embodiment, the multi-mode seeker includes a focal plane array and a bi-modal processing system. The focal plane array includes a detector array and a Read-Out Integrated Circuit (ROIC) operatively coupled to the detector array. The bi-modal processing system is operatively coupled to ROIC and is switchable between: (i) an imaging mode wherein the bi-modal processing system generates video data as a function of signals received from ROIC indicative of irradiance across the detector array, and (ii) a semi-active laser guidance mode wherein the bi-modal processing system generates line-of-sight data as a function of signals received from ROIC indicative of laser pulses detected by the detector array and qualified as corresponding to the predetermined laser designator.

An infared-based scope configured to obtain and display video imagery that allows a user to estimate wind speed and direction over a trajectory to a target based on observed air motion in the video imagery. In certain examples, the scope further includes electronics configured to calculate the wind speed using video image processing techniques.

Embodiments of a gimbaled system with an optical coud&#xe9; path and method for transferring data are generally described herein. In some embodiments, the gimbaled system includes optical coud&#xe9; path to provide a data communication path with a gimbaled payload, an on-gimbal communication laser to transmit modulated camera data via the coud&#xe9; path, and an off-gimbal communication detector to detect the camera data received via the coud&#xe9; path. In some embodiments, the optical coud&#xe9; path may include at least two mirrors to provide a bi-directional communication path through an azimuth axis and an elevation axis of the gimbaled payload.
