  • Low Z-height projection system for projecting structured light for 3D imaging
    Patent number: 8870390
    Abstract: A low Z-height projection system includes a display panel for displaying a grating pattern that has gratings extended in a first direction. A projection lens system is also included and projects the grating pattern displayed on the display panel onto a surface. The projection lens system is a truncated circular lens system that has a first lens width in the first direction and a second lens width in a second direction. The first lens width is less than the second lens width. The first and second directions are orthogonal.
    Type: Grant
