    摘要： A method for monitoring the processing of a workpiece includes directing an incident laser beam onto the workpiece and measuring a signal emitted from the workpiece. At least two signals are generated by a detector based upon the emitted signal. A workpiece processing quality is determined based upon the ratio of the two output signals and a magnitude of one of the two outputs.

    摘要： A method for determining a distance between a first piece and a second piece includes measuring, at the first or second piece, an AC signal, and determining the distance based on the measured AC signal. A system for determining a distance between a first piece and a second piece includes a measuring device adapted to measure, at one or both of the first and second piece, an AC signal, and a signal processing device adapted to determine the distance based on the measured AC signal. The AC signal includes a DC offset.

    摘要： A method for determining a distance between a first piece and a second piece includes measuring, at the first or second piece, a first signal at a first frequency, and measuring, at the first or second piece, a second signal at a second frequency. The second frequency is different from the first frequency. The distance is determined based on the measured first and second signals.

    摘要： A flashlamp provides a ruggedized yet simple-to-manufacture construction capable of operating at high average output power over a long life. The flashlamp construction includes a glass tube (12) with an electrode assembly (24) detachably secured to each end. The electrode assembly includes an end cap (26) to which an electrode support (28) is attached, with a first end (32) of the electrode support protruding inside of the glass tube, and a second end (44) of the electrode support protruding outside of the glass tube. The electrode support (28) is made from a suitable electrical conductor. An electrode (34) is threaded onto the first end of the electrode support (28) without the use of brazing or other attachment techniques that might introduce impurities. An electrode lug (36) is attached to or near the second end of the electrode support, outside of the glass tube, and provides a means for making electrical contact with the electrode (34). The end cap includes threads (30) so as to engage corresponding threads (22) on the inside of an attachment ring (16). One attachment ring is secured and sealed to each end of the glass tube. The electrode assemblies are attached to each end of the glass tube by simply threading the end caps into the attachment rings. An indium washer (42) placed between the end cap and attachment ring effectuates a vacuum seal between the end cap and glass tube.
