Militaire Toepassingen Van Adaptieve Optiek (Military Applications of Adaptive Optics)
Abstract
In this project the benefits of adaptive optics for military applications are assessed. Adaptive optics can be used in electro-optical camera systems and it can be used in laser systems such as directed infrared counter measure systems. In a WEAG project JP8.11 on Precision Laser Beam Steering the benefits of adaptive optics for long range target identification and DIRCM have been evaluated. The findings of the study group are reported in TNO report FEL-04- Al 02. In this project we have studied some of the questions raised in JP8.11 in more detail. The first question is for which optical detection systems adaptive optics can bring some benefits. It was concluded that only for lenses with very large focal numbers and therefore very small field of view adaptive optics can be beneficial. This is caused by the very small atmospheric `iso-planatic' patch which is typical of the order of 1 mrad. We have also studied the influence of atmospheric or plume turbulence on the jam modulation pattern. We have found that plume turbulence levels can severely distort the jam pattern, thus increasing the break-lock time or making the jamming ineffective. This aspect will be further studied in an EDA project.
