In this paper we present a novel image-based 3D surface reconstruction technique that incorporates both reflectance and polarisation features into a variational framework. Our technique is especially suited for the difficult task of 3D reconstruction of rough metallic surfaces. An error functional consisting of several error terms related to the measured reflectance and polarisation properties ...

Wepresent optical and infrared photometric observations of theBe/X-raybinary systemXPersei/4U0352+30during the past decade, covering the entire phase change from Be to OB star and back. Intrinsic colours are derived based on observations during the disk-less phase, giving E(B–V)=0.36±0.02, (B–V)0=–0.22±0.02 and (U–B)0=–1.05±0.02, suggesting a B0V star at a distance of 900pc±300pc and an extinct...

The linear polarisation of the Crab pulsar and its close environment was derived from observations with the high-speed photo-polarimeter OPTIMA at the 2.56-m Nordic Optical Telescope in the optical spectral range (400–750 nm). Time resolution as short as 11 μs, which corresponds to a phase interval of 1/3000 of the pulsar rotation, and high statistics allow the derivation of polarisation detail...

An extended analysis of some instrumental polarisation sources has been done, as a consequence of the renewed interest in extremely sensitive polarisation measurements stimulated by Cosmic Microwave Background experiments. The case of correlation polarimeters, being them more suitable than other configurations, has been studied in detail and the algorithm has been derived to calculate their int...

Precise knowledge of all beam parameters is crucial to fully exploit the physics potential of the International Linear Collider (ILC). A sufficiently accurate measurement of the beam polarisation can only be achieved using dedicated high energy Compton polarimeters combined with well-designed Cherenkov detectors. The requirements have been evaluated and a suitable Cherenkov detector prototype h...
