    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.

    摘要： A rotary optical position encoder for detecting angular position includes a light source, a monolithic scale disk including an optical scale pattern, a monolithic reticle substrate including sets of reticle aperture patterns between the light source and the scale disk, detection and conversion circuitry, and digital processing circuitry. The light source, scale disk, reticle substrate, and detection and conversion circuitry form a plurality of optical sub-encoders at angular positions about the rotational axis, each sub-encoder having an optical path extending from the light source to the detection and conversion circuitry via a respective set of reticle aperture patterns and the optical scale pattern. The digital processing circuitry is operative to combine digital position output values of the sub-encoders to generate an encoder position output value. The optical sub-encoders can include incremental position encoders that provide high-resolution position indications with improved thermally stability due to the use of a shared reticle substrate. Additional optical sub-encoders provide zero-reference or “index” indications as well as a coarse absolute position.

    摘要： A limited rotation motor optical scanning system is disclosed that includes a limited rotation motor scanner, a digital controller servo system, a position feedback unit, a wide angle compensation unit, a digital processor, and an adjustment unit. The limited rotation motor scanner element is adapted for directing an energy beam to at least one location within a field of view. The digital controlled servo system is adapted for controlling motion of the limited rotation motor scanner element in accordance with a servo command waveform. The position feedback unit is for providing a position feedback signal indicative of a rotational position of the limited rotation motor scanner element. The wide angle compensation unit is for receiving the position feedback signal and for providing a boost signal that is representative of a boost factor that compensates for torque constant variation with the rotational position of said limited rotation motor scanner element. The digital processor is for providing a set of control parameters for use during the command waveform in conformance with which the command waveform will be employed to control motion of the limited rotation motor scanner element. The adjustment unit is for providing an adjusted output signal responsive to the control parameters and responsive to the boost signal to control the motion of the limited rotation motor scanner element while compensating for torque constant variation with the rotational position of the limited rotation motor scanner element during the command waveform.

    摘要： An optical position encoder employs spatial filtering of diffraction orders other than +/−1st diffraction orders for greater accuracy. The encoder includes a light source, a scale including a diffractive scale pattern, an optical detector adjacent to the scale, and first and second spaced-apart diffraction gratings between the light source and the scale. The gratings and scale are configured to spatially separate +/−1st diffraction orders from other diffraction orders and to direct the +/−1st diffraction orders along respective optical paths. The optical paths diverge from the first grating to respective locations on the second grating that are separated by more than the beam width of the source light beam. The optical paths further converge from the locations on the second grating to an area of the scale adjacent to the detector, and then extend from the area of the scale to the detector to create an interference pattern as a function of the relative position between the scale and the light source. Preferably, higher diffraction orders are separated by total internal reflection at the first diffraction grating.
