Free Space Optical (FSO) wireless data links are attractive alternatives to RF communications. This technology could
enable vision around corners or barriers, and allow covert, secure, and wireless distribution of scope images to other
squad helmet mounted displays (HMDs), with minimal additional hardware to the current equipment. A major design
challenge for FSO links in personnel applications is ensuring line of sight (LoS) between transmitter and receiver. This
work captures warfighter helmet and gun movement using video motion tracking in a typical application for FSO data
links. A method to simulate transmitter and receiver on the warfighter helmet and gun scope and analyze LoS and FOV
is presented. This method allows optimization of FSO data link placement and provides requirements for future FSO
technology. The initial results suggest that to meet 100% of the threshold requirements, the vertical FOV of a receiver
must be 80° and the horizontal FOV must be 60° and oriented 10° in pitch and -7.5° in yaw. Simulating a FSO link with horizontal and vertical FOV of 60° shows expected performance using a visual method from a helmet mounted camera.
Additionally, the FOV of the transmitter and receiver can be visualized with arbitrary FOV, position, and orientation.
The development, integration and testing of a compact system for wide-area persistence surveillance in dedicated
maritime environments is presented. The system is based around a large-format, 2560 x 512 pixel focal plane array,
high dynamic range (16 bit), mid-wave infrared (MWIR) imager operating at 30 Hz that is equipped with a 90°
horizontal field-of-view (HFOV) lens. The digitized image data is fed to a standard commercial-off-the-shelf (COTS)
workstation equipped with a graphical processing unit (GPU) that is used to perform image de-warping, non-uniformity
corrections, and algorithms for real-time object detection and tracking (NRL Harbor Tracking Software-NRLHaTS). Data is presented from several field experiments that illustrate the capabilities of the integrated system.
As focal plane array technologies advance and imagers increase in resolution, display technology must outpace the
imaging improvements in order to adequately represent the complete data collection. Typical display devices tend to
have an aspect ratio similar to 4:3 or 16:9, however a breed of Wide Field of View (WFOV) imaging devices exist
that skew from the norm with aspect ratios as high as 5:1. This particular quality, when coupled with a high spatial
resolution, presents a unique challenge for display devices. Standard display devices must choose between resizing
the image data to fit the display and displaying the image data in native resolution and truncating potentially
important information. The problem compounds when considering the applications; WFOV high-situationalawareness
imagers are sought for space-limited military vehicles. Tradeoffs between these issues are assessed to the
image quality of the WFOV sensor.
