摘要： A scanning apparatus for predictive shimming includes a scanning platform. The scanning apparatus also include a first scanner, coupled to the scanning platform, and a second scanner, coupled to the scanning platform. The scanning platform is configured to move the first scanner and the second scanner together along an X-axis and a Z-axis. The scanning platform is also configured to move the first scanner and the second scanner independent of and relative to each other along a Y-axis and a Z-axis. A first field of view of the first scanner and a second field of view of the second scanner at least partially overlap when the first scanner and the second scanner move in opposite directions along the Y-axis.

摘要： A catheter procedure system includes a base and a robotic mechanism having a longitudinal axis and being movable relative to the base along the longitudinal axis. The robotic mechanism includes a robotic drive base including at least one drive mechanism, a cassette operatively secured to the robotic drive base, a rigid guide coupled to the cassette and fixed relative to the robotic mechanism and a flexible track having a distal end, a proximal end and a plurality of reflective sections. At least a portion of the flexible track is disposed within the rigid guide. The robotic mechanism also includes a position detector mounted to the robotic drive base and positioned beneath the flexible track. The position detector is configured to detect light reflected off of the reflective sections of the flexible track and to determine the position of the distal end of the flexible track based on the detected reflected light.

摘要： The present invention relates to the field of vehicle correction, and provides a calibration system and a calibration bracket thereof. The calibration bracket includes: a base, a stand assembly and a beam assembly. The stand assembly is fixedly connected to the base. The beam assembly includes a first beam portion, a second beam portion and a connecting portion, the connecting portion being mounted to the stand assembly, one end of the connecting portion being hinged to the first beam portion, and the other end of the connecting portion being hinged to the second beam portion. The first beam portion and the second beam portion can respectively rotate toward each other relative to the connecting portion, so that the beam assembly can be folded. The first beam portion and the second beam portion can also respectively rotate away from each other relative to the connecting portion, so that the beam assembly can be unfolded. In the foregoing structure, the first beam portion and the second beam portion can respectively rotate toward each other relative to the connecting portion, so that the beam assembly is folded, thereby reducing a volume of the calibration bracket to facilitate shipment.

摘要： Methods and systems for characterizing dimensions and material properties of semiconductor devices by transmission small angle x-ray scatterometry (TSAXS) systems having relatively small tool footprint are described herein. The methods and systems described herein enable Q space resolution adequate for metrology of semiconductor structures with reduced optical path length. In general, the x-ray beam is focused closer to the wafer surface for relatively small targets and closer to the detector for relatively large targets. In some embodiments, a high resolution detector with small point spread function (PSF) is employed to mitigate detector PSF limits on achievable Q resolution. In some embodiments, the detector locates an incident photon with sub-pixel accuracy by determining the centroid of a cloud of electrons stimulated by the photon conversion event. In some embodiments, the detector resolves one or more x-ray photon energies in addition to location of incidence.

摘要： Prediction of a distribution of light in an illumination pupil of an illumination system includes identifying component(s) of the illumination system the adjustment of which affects this distribution and simulating the distribution based on a point spread function defined in part by the identified components. The point spread function has functional relationship with configurable setting of the illumination settings.

摘要： A method for determining an arrangement of a sample object in an optical device comprises illuminating the sample object from at least one first illumination direction and illuminating the sample object from at least one second illumination direction. The method also comprises carrying out a correlation between data which are indicative of at least one section of an image of the sample object under illumination from the at least one first illumination direction and data which are indicative of at least one section of an image of the sample object under illumination from the at least one second illumination direction. The method also comprises determining the arrangement of the sample object in relation to a focal plane of the optical device based on the correlation.
