“…During operations in Iraq and Afghanistan, there was a particular emphasis on operations in self-induced dust, so called "brown-out" conditions ( Figure 5, from [20]). However, as operations in those regions wind-down DVE operations in a wider range of obscurants are of interest.…”

MMW and THz sensors offer unique imaging capabilities and challenges. This paper will provide a brief discussion of illumination, propagation, and resolution in these and adjacent bands, followed by a discussion of some application areas for these sensors, in particular imaging in Degraded Visual Environments (DVE), stand-off screening and chemical detection, and surveillance and monitoring. Comparisons with other sensing modalities will be provided discussing some of the relative strengths and weaknesses of MMW & THz sensing compared to these other modalities.

“…In 2006 and 2007 Boeing performed flight testing on a small MD-530 helicopter to demonstrate an ESVS with colored conformal symbology in DVE. 30 Sensory information from a variety of fixed and turreted sensors and symbology were simultaneously available to the pilot on a monochrome, semi-transparent HMD and to a remote user through full-color, virtual reality glasses. Sensor imagery was stitched in real-time and integrated with color textured synthetic imagery and color symbology, including a purple highway-in-the-sky, gridded domes for obstacles and a green pitch ladder.…”

Review of colored conformal symbology in head-worn displays

The usage of conformal symbology in color head-worn displays (HWDs) opens up a range of new possibilities on modern flight decks. The capability of color augmentation seems especially useful for low flights in degraded visual environments. Helicopter flights in these conditions, including brownout by swirling dust or sand particles, can often lead to spatial disorientation (SD) and result in a significant amount of controlled flight into terrain (CFIT). While first generation color-capable conformal displays are deployed, practical guidelines for the use of color in these see-through interfaces are yet to be established. A literature survey is carried out to analyze available knowledge of color use in conformal displays and to identify established methodologies for human-factors experimentation in this domain. Firstly the key human factors involved in color HWDs are outlined, including hardware design aspects as well as perceptual and attentional aspects. Secondly research on color perception is mapped out, focusing on investigations of luminance contrast requirements, modeling of color space blending and development of color correction solutions. Thirdly application-based research of colored conformal symbology is reviewed, including several simulations and flight experiments. Analysis shows that established luminance contrast requirements need to be validated and that performance effects of colored HWD symbology need more objective measurements. Finally practical recommendations are made for further research. This literature study has thus established a theoretical framework for future experimental efforts in colored conformal symbology. The Institute of Flight Guidance of the German Aerospace Center (DLR) anticipates conducting experiments within this framework.

Boeing has developed algorithms and processing to detect power lines and cables in passive imagery from a wide variety of different sources. The algorithm has been demonstrated with imagery from visible, medium and long wave infra-red (MWIR and LWIR), and Passive MilliMeter Wave (PMMW) sensors. Flight demonstrations of the real-time system have been performed with both visible and LWIR image sensors. In the flight demonstrations, an LWIR image sensor was used for both day and night detection in both rural and urban settings with detection ranges in excess of 15,000'. The processing system is capable of processing image sizes up to 1024x1024 pixels at 30 frames per second.
