• 論文の詳細を見る

• This paper describes high signal-to-noise ratio and high resolution detection techniques for photopryoelectric thermal wave imaging equipment. A high signal-to-noise ratio technique is mainly achieved by realizing a very low-noise first stage pre-amplifier and its assembling technique and by the use of very low noise second stage amplifier. High resolution detection is achieved by using a metal probe tip with a very small diameter. This equipment could be achieved mainly due to the high signal-to-noise technique and the finite element method (FEM) analysis. A high-fidelity tomographic image reconstructed by these techniques is also shown.
