(author), van de Pol, M. (author)Optical satellite communications is a maturing technology to enable word-wide access to high throughput internet. In the past years a lot of effort has been taken to increase the applicability and the TRL of this technology. In collaboration with industry, TNO initiated several developments for space and ground technologies. Many of these...conference paper 2021

(author), Lubbers, L.A. (author)Metamaterials is a rapidly developing field of research. It offers the prospect of material properties that do not exist in regular materials and which might be useful for overcoming hurdles in current mechatronic system design. Stimulated by the progress in additive manufacturing (AM) that has enabled fabrication of materials with complex...article 2020

Test results of lateral load insensitive FBGs embedded in composites to suppress spectral distortionCheng, L.K. (author), Hagen, R.A.J. (author), Vosteen, L.L.A. (author), Atli-Veltin, B. (author), Toet, P. (author), Molkenboer, F.T. (author), van Kempen, F.C.M. (author), van der Togt, O.E. (author), Jedynska, A.D. (author), Jansen, T.H. (author)Composite constructions are indispensable in current and future society. Fiber Bragg Gratings (FBGs) embedded in composite need to be carefully aligned with the material fibers to reduce inhomogeneous lateral load exerted onto the FBG which occurs due to the inhomogeneous nature of composite materials. Inhomogeneous load causes distortion of the...conference paper 2019
