摘要： There is provided a maser environmental-analysis system (10) which comprises a plurality of environmental data inputs indicative of a plurality of environmental characteristics of an environment (14) in which a maser is to be used, which feed into a maser-suitability determinator (16). The maser-suitability determinator (16) determines an operational environment of the maser to be used. There is also a plurality of reference-environment data sets (22) and a plurality of environmental-modifier data sets (24), and the maser-suitability determinator (16) determining an operational environment of the maser to be used based on these inputs to analyse a suitability of the maser for use in the environment (14). An output circuit (26) is also supplied for providing a data output indicative of the suitability of the maser to be used to a user of the maser environmental-analysis system (10).

摘要： A system (100) for laser treatment of the eye comprises one or more diffractive optical elements (12)(56a)-(56k) for producing unique treatment segments within an ablation zone (132) on the eye. The treatment segments may be annular (Ia)-(Ii), pie shaped (2a)-(2g), or have other geometries or patterns selected to apply energy in a particular manner, usually in a non-overlapping manner so that energy dosages can be precisely controlled. In a first embodiment of the system (100), a single diffractive optical element (12) is used, and a beam expander (22) expands or converges the beam to achieve the different treatment segments. In a second embodiment, a plurality of diffractive optical elements (56a)-(56k) are used, each of which produces a single treatment segment.

摘要： A fully integrated automated laser weld process control system (LWPCS) and method of controlling the fabrication of structural parts, particularly for shipbuilding and other industries. The LWPCS defines joint and weld quality attributes as process control variables and integrates these weld quality variables, along with the more traditional process parameters such as laser power, wire feed, GMAW voltage and active seam tracking, into a closed-loop monitoring and control system. The LWPCS includes a central processor and a plurality of subsystems that control laser beam positioning, vision-based monitoring and image processing, active weld-quality monitoring and inspection, adaptive beam delivery, and seam tracking. Cross-communication between subsystems is managed by the central processor. In addition to process control, the system extracts weld quality attributes during the weld process and provides immediate documentation of the weld quality.
