Abstract :
By using a 3D interferometric array to detect point sources of equal intensity, it is possible to detect a difference in distance much more accurately. Also by tuning the depth layout of the array to be log periodic it is possible to increase the resolution of the image. The concept can be extended to image 3D objects.
