Grating optical
WebAn optical read head flying over a track emits a probe beam, and recombines the diffraction products of the grating track which are detected as an interference signal [1]. Unlike in … WebA grating pair in its simplest form (the so-called Treacy configuration, see Fig. 1) introduces negative dispersion due to the difference in the optical path undergone by the different wavelengths. At the output of a grating pair, however, we have a spatially incoherent beam.
