    According to a blog article (translation from Japanese)...

    It looks like Olympus has a Patent pending for a design for a sensor which uses a second layer of image sensors to detect phase difference of light hitting the sensor at every pixel position.
    This could give a quantum leap in focus tracking, but also allow 3d mapping of the whole image, and allow fine tuning of image depth afterwards... In other words, the very narrow depth of field available to large frame format cameras would be available to professional m4/3rds shooters if they want it.
    Olympus patents pending to achieve by the imaging element of the stacked image plane phase difference AF. By using the phase difference detection imaging an eye, the second layer further, it is possible to image surface phase difference AF without deterioration of the resolution.
