N2 - In this paper we generalize a method, proposed for model independent time imaging, to calculate seismic images in depth without performing velocity analysis or using a priory knowledge of the exact subsurface model. By analogy to the use of Feynman path integrals in waveform modeling, we develop an algorithm for depth imaging by summation of elementary signals over a sample of all possible paths between source and receiver. The constructive and destructive interference of these signals, produces an image of the subsurface.
