OBSERVATION TECHNOLOGY BY COHERENT WAVE

摘要

A technology for reducing the influence of a wave acting on an observation object when observation is carried out by causing a wave to act on the observation object. A plurality of waves having coherence are generated and the intensity of a wave acting on the observation object (SPC) is reduced to one half or less of the average intensity of waves at the position of the observation object by causing interference of the plurality of waves. At least one of the plurality of waves interacted with the observation object (SPC) is observed.
