First pulsar observations with the MAGIC telescope

An optical method and system are presented for use in measurement of isolated features of a structure. According to this technique, Back Focal Plane Microscopy (BFM) measurements are applied to a structure and measured data indicative thereof is obtained, wherein the BFM measurements utilize dark-field detection mode while applying pinhole masking to incident light propagating through an illumination channel towards the structure, the measured data being thereby indicative of a scattering matrix characterizing scattering properties of the structure, enabling identification of one or more isolated features of the structure.
