SD Optics Depth Sensing Camera

SD Optics publishes two videos of depth sensing by means of fast focus variations of its MEMS lens:

  1. it seems to me the optical path gets modulated so that the point of sharpness moves around multiple depths. in a result a depth curve of the sharpness can be determined and the peak of that curve gives the estimated depth of the object.

    evidently the provided video sequences are showing only depth information for areas where sufficient texturing is on the objects. the measurement method seems to work more or less even for object edges.

  2. Yes. Our single lens system can be repeatedly infinitely variable focus. The demonstration system shown here is able to repeatedly and infinitely vary the preset focal length.
    By this, the depth is sensed by the algorithm using the point where the sharpness is matched.

    The operation structure is as follows.

    It is helpful to refer to existing videos.
