  • Patent number: 11788833
    Abstract: Method and system for defining basis functions for fitting distortions of profiles of objects in a batch, that has undergone a fabrication process, in a manner adaptable to the fabrication process to reduce the errors between profiles approximated with the use of such basis functions and actual object profiles. Process-specific individual basis functions are defined based on spatially-dense measurement of objects from training sub-set of the batch and applying learning algorithm to results of such measurement. Advantages of process-adaptable basis functions over generic basis functions for fitting distortion shapes of objects include higher accuracy of fitting either at larger or a fewer locations across the object.

  • Patent number: 11786118
    Abstract: In an ophthalmic imaging system an image imaged by an imaging section for a right eye is formed as an imaging image on a display, and then displayed through a right-eye optical unit and a reflection member. An image imaged by an imaging section for a left eye is formed as an imaging image on a display, and then displayed through an optical unit and the reflection member. This thereby enables the object to be visually inspected as a three-dimensional image by the observer viewing the right-eye imaging image and the left-eye imaging image, which differ from each other according to the parallax therebetween, by viewing the respective images through right and left eyes.
