  1. Distance Estimation of Hidden Objects Based on Acoustical Holography by applying Acoustic Diffraction of Audible Sound Haruhiko Niwa, Tetsuya Ogata, Kazunori Komatani and Hiroshi G. OkunoDepartment of Intelligence Science and Technology, Kyoto University, Japan • Occlusion is a problem for range finders. • We applied acoustic diffraction of audible sound. • Our method is based on time-of-flight and acoustical holography. • Our method was effective for raging two objects of the same size within 1.2 m Our system
