  • Patent number: 11671724
    Abstract: An image sensor may include a pixel array, row control circuitry, and column readout circuitry. The row control circuitry may operate the pixel array in a global shutter mode of operation. In particular, timing control circuitry may provide global timing clock signals associated with a global photodiode reset event and a global photodiode charge transfer event to row driver circuitry providing control signals to each row in the array. Each driver circuitry may include a time delay circuit that delays the global timing clock signal by different amounts across the rows. Therefore, these global events may be offset on a per-row or per-row group basis, thereby mitigating power surges associated with global events. Further, by offsetting the global photodiode reset and charge transfer events using the same delay for a given row, the same global integration time may be preserved across different rows.

  • Patent number: 11650125
    Abstract: A method and apparatus for a structured light measuring device, having a preferable VCSEL array in its previous illuminated cross plane, using the laser array to be projected through said device's objective and collect the reflected beams through the same objective lens. A motorized stage is attached to the objective focusing, enabling back and forth focusing on different external planes. A software algorithm running on a computer device will analyze the reflected laser beam and find its central point and further translate it to angular deviations, similar to Autocollimation principles. Furthermore, this could be displayed as a cross on the user GUI for better user interface. The focusing function has the capability to focus the laser array at various planes, and analyze if the reflected beam is at its best focal point or deviates. By moving the focal point back and forth, a 3-D reconstruction can be achieved, preferable for lenses and calculating the center location relative to the device's line of sight.
