  • Patent number: 10215707
    Abstract: An inspection system for inspection a surface of a substrate, the inspection system may include an interface for holding the substrate; a movement mechanism for moving the interface, thereby moving the substrate between different positions; a bright field light source that is configured to illuminate different bright field illuminated parts of the surface of the substrate when the substrate is positioned at the different positions; at least one dark field light source that is configured to illuminate different dark field illuminated parts of the surface of the substrate when the substrate is positioned at the different positions; and a camera that is configured to: (a) generate bright field detection signals in response to light that is detected by the camera as a result of the illumination of the different bright field illuminated parts; and (b) generate dark field detection signals in response to light that is detected by the camera as a result of the illumination of the different dark field illuminated par

  • Patent number: 9756313
    Abstract: A triangulation system comprising an area camera, a communication interface, a first image processing module, a second image processing module; wherein the area camera is arranged to obtain, at an acquisition rate, a stream of images of illuminated regions of an object; wherein the area camera is prevented from performing height calculations; wherein the communication interface is arranged to convey, in real time thereby in correspondence to the acquisition rate, the stream of images from the area camera to the first image processing module; wherein the first image processing module is arranged to process, in real time, the stream of images to provide first compressed information; wherein the second image processing module is arranged to process, at a non-real time image processing rate, the first compressed information to provide height information indicative of heights of at least the illuminated regions of the object.
