  1. 1. On the Military Utility of Spectral Design in Signature Management : a Systems Approach

    Författare :Kent Andersson; Jouko Vankka; Gunnar Hult; Hans Kariis; Hans Liwång; Harold Lawson; Jari Hartikainen; Försvarshögskolan; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; military utility; survivability; signature management; systems engineering; camouflage; Low Observable Technology; spectral design; multi-spectral; Försvarssystem; Military Technology;

    Sammanfattning : There is an ongoing duel between military sensor development and developments in signature management. The last decade, with warfare characterized by joint expeditionary operations and asymmetry, has favored sensors. LÄS MER

  3. 2. Optical Studies of Bio-inspired Materials for Camouflage

    Författare :Christina Åkerlind; Kenneth Järrendahl; Hans Arwin; Hans Kariis; Karin Stein; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In the ongoing sensor-camouflage duel, new functionalities and sensing abilities are continuously incorporated in detector devices, requiring new capabilities on the camouflage side. The aim of this work is to contribute to improved camouflage including low polarization detectability in wavelength regions with both visible and invisible light. LÄS MER

  5. 4. Life at stake when playing hide and seek : Concealing effects of prey colouration and visual backgrounds

    Författare :Marina Dimitrova; Merilaita Sami; Innes C. Cuthill; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; predation; adaptive prey coloration; camouflage; concealment; crypsis; background matching; disruptive colouration; distractive markings; Terrestrial ecology; Terrestrisk ekologi; zoologisk ekologi; Animal Ecology;

    Sammanfattning : A prey animal can use different strategies to avoid becoming eaten by predators. One such widely recognised strategy is the use of body colouration to decrease the risk of becoming detected, i.e. cryptic colouration. LÄS MER

  7. 5. Optical Studies of Materials for Spectral Design

    Författare :Christina Åkerlind; Kenneth Järrendahl; Hans Arwin; Hans Kariis; Isak Engquist; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Optical material properties have been studied in a wide wavelength range. Theaim is future use of spectral design for camou age. The main characterization techniques used in this work are Refection Spectroscopy, Scatterometry (BRDF) and Mueller Matrix Ellipsometry. LÄS MER
