    Abstract: A scanning observation apparatus (10) deflects illumination light with an actuator (25) through an illumination optical system (26) to scan an object (32), subjects light from the object (32) to photoelectric conversion with an optical detector (44), performs processing with an image processor (46), and displays an image of the object (32) on a display (60). A memory (35) stores information on optical characteristics related to chromatic aberration of magnification of the illumination optical system (26) relative to light of predetermined colors. A scanning pattern calculator (45) calculates a scanning pattern, on the object (32), of light of each color using the information. Using the scanning pattern, the image processor (46) calibrates a plot position yielded by a photoelectric conversion signal from the optical detector (44) for light of each color and generates an image of the object (32), thereby more easily correcting the chromatic aberration of magnification.

  • Patent number: 10449624
    Abstract: Methods and systems for manufacturing a three-dimensional product. Fabrication of a three-dimensional part from a powder spread over a work table as a powder bed can be initiated. The fabrication process can be paused to cool down the work table to room temperature to obtain access to the three-dimensional part for post-processing operations such as, for example, embedding external artifacts. Fabrication can continue by preheating the powder rather than the work table until fabrication of the three-dimensional part is complete. A damaged part may be placed within the powder bed, wherein the fabrication process can be directly initiated to achieve part repair. Additionally, a material of the same part's composition can be used or a different material utilized to render the part better than new. Access to the three-dimensional part allows embedding of a foreign object in the three-dimensional part within the powder bed while the three-dimensional part remains non-finished.

  • Patent number: 9491448
    Abstract: Systems and methods for measuring a surface of an object. The system, in one embodiment, includes a laser projector device mounted at a fixed location relative to an object being formed by a fabrication process, and a videogrammetry device mounted at another fixed location relative to the object. The laser projector device includes a laser element mounted on a two-axis gimbal assembly, and the gimbal assembly directs laser beams from the laser element onto target points on a surface of the object. The laser projector device measures angles of the laser beams to the target points, while the videogrammetry device simultaneously performs measurements of the target points by capturing video images of the laser beams reflecting off of the target points. A controller processes the measurements from the laser projector device and the videogrammetry device to calculate x, y, z coordinates of the target points in a 3D coordinate system.

  • Patent number: 9349572
    Abstract: An energy dispersive X-ray analyzer is attached to a scanning electron microscope and includes: a SEM controller; a detector; an EDS controller; and a data processor. The data processor generates first and second X-ray mapping image respectively when the SEM controller controls the scanning electron microscope to irradiate the sample with an electron beam under first and second acceleration voltage conditions. The data processor corrects the first X-ray mapping image and the second X-ray mapping image into images that are independent of acceleration voltage condition based on a measurement intensity variation ratio of the X-ray when changed from the first acceleration voltage condition to the second acceleration voltage condition, and controls the display unit to display a difference image between the corrected first X-ray mapping image and the corrected second X-ray mapping image.

    Abstract: Systems configured to inspect a wafer are provided. One system includes an illumination subsystem configured to simultaneously form multiple illumination areas on the wafer with substantially no illumination flux between each of the areas. The system also includes a scanning subsystem configured to scan the multiple illumination areas across the wafer. In addition, the system includes a collection subsystem configured to simultaneously and separately image light scattered from each of the areas onto two or more sensors. Characteristics of the two or more sensors are selected such that the scattered light is not imaged into gaps between the two or more sensors. The two or more sensors generate output responsive to the scattered light. The system further includes a computer subsystem configured to detect defects on the wafer using the output of the two or more sensors.
