Camouflage performance of winter uniforms: photosimulations in the visual spectrum
Mikkelsen, Alexander; Selj, Gorm Krogh; Nielsen, Niels Hygum (2023-10-23)Minimizing electro-optical signatures of soldiers against modern sensors is a challenging task, but a task with high importance and benefits for operative soldiers that need to stay undetected. Optimizing camouflage uniforms ... -
Spectral characteristics of moist birch leaves and synthetic materials: experimental studies and evaluation of models
Mikkelsen, Alexander; Selj, Gorm Krogh (2021-11-09)The optical depth of biomaterials and natural backgrounds varies with their environment and incoming light properties. Deciduous trees, for instance, have canopy thicknesses that vary significantly from one place to another. ... -
Spectral properties of multilayered oak leaves and a camouflage net: experimental measurements and mathematical modelling
Mikkelsen, Alexander; Selj, Gorm Krogh (2021-09-21)The development of state-of-the-art surveillance technology forces nations to develop camouflage with advanced capabilities. Owing to the abundance and wide distribution of leaves, their spectral properties are often ... -
Spectral reflectance and transmission properties of a multi-layered camouflage net: Comparison with natural birch leaves and mathematical models
Mikkelsen, Alexander; Selj, Gorm Krogh (2020-09-20)With improved specifications and capabilities of modern sensors and detectors, concealment is an increasingly challenging endeavor. Concealment from modern sensors requires advanced camouflage material that can provide low ... -
Spectral reflectance measurements of snow and snow covered objects: experimental studies compared with mathematical models
Selj, Gorm Krogh; Mikkelsen, Alexander (2021-09-12)In this study, we have investigated reflectance spectra of different snow types under various conditions. Snow reflectance is interesting from a camouflage point of view as snow covers large land areas in many parts of the ...
