摘要： A system for monitoring the condition of elongate structural elements, for example, railway rails, and a method of designing and manufacturing the system is disclosed. The method includes identifying and selecting suitable modes of propagation and signal frequencies that can be expected to travel large distances through an elongate structural element; designing a transducer that will excite the selected mode at the selected frequency; numerically modelling the transducer as attached to the elongate structural element; validating the transducer design by analysing a harmonic response of the selected mode of propagation to excitation by the transducer, and manufacturing one or more transducers for use in the system.

摘要： A method and apparatus for performing a modal decomposition of a laser beam are disclosed. The method includes the steps of performing a measurement to determine the second moment beam size (w) and beam propagation factor (M2) of the laser beam, and inferring the scale factor (wO) of the optimal basis set of the laser beam from the second moment beam size and the beam propagation factor, from the relationship: wO=w/M2. An optimal decomposition is performing using the scale factor wO to obtain an optimal mode set of adapted size. The apparatus includes a spatial light modulator arranged for complex amplitude modulation of an incident laser beam, and imaging means arranged to direct the incident laser beam onto the spatial light modulator. Fourier transforming lens is arranged to receive a laser beam reflected from the spatial light modulator. A detector is placed a distance of one focal length away from the Fourier transforming lens for monitoring a diffraction pattern of the laser beam reflected from the spatial light modulator and passing through the Fourier transforming lens. The apparatus performs an optical Fourier transform on the laser beam reflected from the spatial light modulator and determines the phases of unknown modes of the laser beam, to perform a modal decomposition of the laser beam.

摘要： A control system for thermo optical control of focus position of an energy beam in an additive manufacturing apparatus has a first doped medium and a second doped medium, each of which is optically transparent and doped with a dopant. The first doped medium has a positive thermo-optical coefficient (dn/dT) and the second doped medium has a negative thermo-optical coefficient (dn/dT) and is in series with the first doped medium. An energy beam input or coupling is configured to generate or receive an energy beam that is required to be controlled, the energy beam being within a first wavelength range and directed towards the first and second doped mediums. An absorbed beam input or coupling is configured to generate or receive at least one absorbed beam in a second wavelength range which is different from the first wavelength range, the absorbed beam being directed towards the first and second doped mediums. The first and second doped mediums have a higher beam absorption characteristic in the second wavelength range than in the first wavelength range, causing the absorbed beam to have a higher absorption than the energy beam in the first and second doped mediums and the first and second doped mediums each have a coating which allows transmission at both the first and the second wavelength ranges.
