- 論文の詳細を見る
The association between the pulse shape of a probe pulse and phase modulation in the proposed method of phase information transmission by utilizing a phase conjugate is studied by simulation. As a result, it is found that phase modulation is possible irrespective of both pulse waveform and carrier signal type, and that the phase of the reconstructed pulse at the sound source varies according to the amount of phase modulation added at the array. Some carrier signals conserve such a particular position as an inflection point, which can be utilized as a reference point of the phase.
