  • Patent number: 10918272
    Abstract: An otoscope may project a temporal sequence of phase-shifted fringe patterns onto an eardrum, while a camera in the otoscope captures images. A computer may calculate a global component of these images. Based on this global component, the computer may output an image of the middle ear and eardrum. This image may show middle ear structures, such as the stapes and incus. Thus, the otoscope may “see through” the eardrum to visualize the middle ear. The otoscope may project another temporal sequence of phase-shifted fringe patterns onto the eardrum, while the camera captures additional images. The computer may subtract a fraction of the global component from each of these additional images. Based on the resulting direct-component images, the computer may calculate a 3D map of the eardrum.

  • Patent number: 10410366
    Abstract: An imaging system includes an optical unit that captures, from a scene, sets of first images as well as sets of second images. The scene is illuminated with non-structured light when the sets of first images are captured and illuminated with structured light when the sets of second images are captured. A pattern processing unit generates, from the second images, a recovered shadow pattern from a shadow pattern projected onto the scene during illumination with structured light, wherein at least one motion-compensated reference image is used. A depth processing unit obtains depth information on the basis of the recovered shadow pattern.

  • Patent number: 10372845
    Abstract: A method and system are presented for use in scatterometry analysis for a patterned structure. According to this technique, a model of a patterned structure is provided comprising a selected number of virtual segment data pieces indicative of a respective number of segments of the patterned structure along Z-axis through the structure. Each of the segment data pieces is processed for determining a matrix [?n] comprising Z-axis derivatives of electromagnetic fields' response of the segment to incident field based on Maxwell's equations' solution, and transforming this matrix [?n] into an approximated response matrix [?n] corresponding to the electromagnetic field interaction between two different points spaced along the Z-axis. The transformation is preferably carried out by a GPU, and comprises embedding said matrix [?n] in a series expansion of said matrix exponential term [?n].
