    摘要： A position encoder provides one or more trigger outputs based on position signals developed within the encoder, in addition to traditional position output signals used by other system components such as a motion controller. The trigger outputs may be used directly by a triggered device, bypassing the motion controller and obviating any separate trigger generation electronics. The trigger output(s) can be fully synchronous with the encoder's position output signal(s) with essentially no latency or jitter, increasing accuracy and providing improved system performance. The trigger functionality can be incorporated in a variety of encoder types (e.g., absolute and incremental) and technologies (optical, magnetic, inductive etc.), and used in conjunction with different position output signal formats (e.g., quadrature, serial).

    摘要翻译： 除了诸如运动控制器的其他系统组件使用的传统位置输出信号之外，位置编码器还基于在编码器内产生的位置信号来提供一个或多个触发输出。 触发输出可以由触发的设备直接使用，绕过运动控制器并且消除任何单独的触发器电子器件。 触发输出可以与编码器的位置输出信号完全同步，基本上没有延迟或抖动，提高了精度并提高了系统性能。 触发功能可以并入各种编码器类型（例如，绝对和增量）和技术（光学，磁性，电感等），并且与不同的位置输出信号格式（例如，正交，串行）结合使用。

    摘要： A method, system and scan lens for use therein are provided for high-speed, laser-based, precise laser trimming at least one electrical element along a trim path. The method includes generating a pulsed laser output with a laser, the output having one or more laser pulses at a repetition rate. A fast rise/fall time, pulse-shaped q-switched laser or an ultra-fast laser may be used. Beam shaping optics may be used to generate a flat-top beam profile. Each laser pulse has a pulse energy, a laser wavelength within a range of laser wavelengths, and a pulse duration. The wavelength is short enough to produce desired short-wavelength benefits of small spot size, tight tolerance, high absorption and reduced or eliminated heat-affected zone (HAZ) along the trim path, but not so short so as to cause microcracking. In this way, resistance drift after the trimming process is reduced.

    摘要： An energy-efficient method and system for processing target material such as microstructures in a microscopic region without causing undesirable changes in electrical and/or physical characteristics of material surrounding the target material is provided. The system includes a controller for generating a processing control signal and a signal generator for generating a modulated drive waveform based on the processing control signal. The waveform has a sub-nanosecond rise time. The system also includes a gain-switched, pulsed semiconductor seed laser for generating a laser pulse train at a repetition rate. The drive waveform pumps the laser so that each pulse of the pulse train has a predetermined shape. Further, the system includes a laser amplifier for optically amplifying the pulse train to obtain an amplified pulse train without significantly changing the predetermined shape of the pulses. The amplified pulses have little distortion and have substantially the same relative temporal power distribution as the original pulse train from the laser. Each of the amplified pulses has a substantially square temporal power density distribution, a sharp rise time, a pulse duration and a fall time. The system further includes a beam delivery and focusing subsystem for delivering and focusing at least a portion of the amplified pulse train onto the target material.

    摘要： A method and system for laser processing targets of different types on a workpiece are provided. The method includes setting a laser pulse width of one or more laser pulses to selectively provide one or more laser output pulses having one or more set pulse widths based on a first type of target to be processed. The method further includes setting a pulse shape of the one or more output pulses to selectively provide the one or more output pulses having the set pulse shape based on the types of targets to be processed. The method still further includes delivering the one or more output pulses having the one or more set pulse widths and the set pulse shape to at least one target of the first type. The method finally includes resetting the laser pulse width of one or more laser pulses to selectively provide one or more laser output pulses having one or more reset pulse widths based on a second type of target to be processed.
