  • Patent number: 10648919
    Abstract: A metrology apparatus (302) includes a higher harmonic generation (HHG) radiation source for generating (310) EUV radiation. Operation of the HHG source is monitored using a wavefront sensor (420) which comprises an aperture array (424, 702) and an image sensor (426). A grating (706) disperses the radiation passing through each aperture so that the image detector captures positions and intensities of higher diffraction orders for different spectral components and different locations across the beam. In this way, the wavefront sensor can be arranged to measure a wavefront tilt for multiple harmonics at each location in said array. In one embodiment, the apertures are divided into two subsets (A) and (B), the gratings (706) of each subset having a different direction of dispersion. The spectrally resolved wavefront information (430) is used in feedback control (432) to stabilize operation of the HGG source, and/or to improve accuracy of metrology results.

    Abstract: This disclosure relates generally to telecom inventory management, and more particularly to telecom inventory management via object recognition and localization using street-view images. In one embodiment, the method includes obtaining street-view images of a geographical area having telecom assets. The telecom assets are associated with corresponding GPS location coordinates. An object recognition model is applied to the street-view images to detect the telecom assets therein. Detecting the telecom assets includes associating the telecom assets with corresponding asset labels. A real-world location of the telecom assets is estimated in the geographical area by applying triangulation method on a set of multi-view images selected from the street-view images. The set of multi-view images are captured from a plurality of consecutive locations in vicinity of the telecom asset in the geographical area.

  • Patent number: 10341646
    Abstract: A variable focal length (VFL) lens system is provided including a VFL lens, a VFL lens controller, an objective lens, a camera and an optical power monitoring configuration. During a standard workpiece imaging mode, the objective lens transmits workpiece light along an imaging optical path through the VFL lens to the camera, which provides a corresponding workpiece image exposure. During an optical power monitoring mode, the optical power monitoring configuration produces a monitored beam pattern which travels along at least a portion of the imaging optical path through the VFL lens to the camera, which provides a monitoring image exposure. Different monitoring image exposures are acquired at different phase timings of the periodic modulation of the VFL lens, and a dimension of the monitored beam pattern is measured in each monitoring image exposure as related to an optical power of the VFL lens at the corresponding phase timing.

    Abstract: An image pickup apparatus that is capable of obtaining a high-quality image that is focused on an object designated by a user at the time of reproducing an image. A detection unit detects an object from an image obtained by photographing. A first computation unit computes a distance between the object and the image pickup apparatus as an object distance based on a distance map obtained according to the image. A decision unit decides a focus interval that is an interval of in-focus positions at which objects are focused and a focus frequency that is a count of the in-focus positions according to the object distance and a preset condition. A second computation unit computes the in-focus positions according to the object distance, the focus interval, and the focus frequency.
