摘要： An optical scanning unit with a rotatable hologram disc, including a light source, a rotatable hologram disc provided with a plurality of holograms, the holograms being formed concentrically along a radial direction to diffract a beam emitted from the light source by multiple steps, a reflecting member that reflects the beam emitted from the light source and diffracted by one of the holograms into another hologram, and a fixed hologram correcting the diffracted beam incident through the rotatable hologram disc to focus it on a scanning object. In the optical scanning unit, the light passes through the plurality of holograms formed along a radial direction of the rotatable hologram disc so that a scan width can be extended without reducing a scan speed of the optical scanning unit.

摘要： A method and system for assessing the condition of a pipe carrying a fluid is disclosed. The method includes the steps of generating a pressure wave in the fluid being carried along the pipe and detecting a pressure wave interaction signal resulting from an interaction of the pressure wave with a localized variation in pipe condition. The method then involves determining from the timing of the pressure wave interaction signal the location of the localized variation in pipe condition and the extent of the localized variation in pipe condition based on a characteristic of the pressure wave interaction signal.
