PROBLEM TO BE SOLVED: To provide a conversion device which can analyze waves, arriving from various directions, simultaneously with high spatial resolution, while shortening the impulse responce length between a wave source and an observation point.SOLUTION: A conversion device includes a high SN zone formation unit for forming a high SN zone, and M m-th conversion units arranged at different positions near the high SN zone, and converting a wave into a signal, or a signal into a wave, where M is an integer of more than 1, and m=1, 2, .... The waves to be converted or converted in the M m-th conversion units are entirely the same kind of waves. |
