Patent Images

1. An imaging method for producing improved resolution images, comprising:

  • illuminating an object with coherent radiation;

    with a plurality of subapertures, collecting light scattered from the illuminated object;

    coherently detecting the light collected by each of the subapertures;

    digitally reconstructing images from the coherently detected light for a set of the subapertures; and

    digitally co-phasing the subapertures in the set of the subapertures using an image sharpness metric to form an image of the object comprising the digitally reconstructed images.
