全ての周波数の振動分布を可視化するリアルタイム振動イメージャの開発

抄録

We have developed a real-time vibration imager that can simultaneously visualize vibration distributions at all frequencies by calculating frequency responses of brightness distributions, sub-pixel displacements, and velocity distributions through parallel GPU implementation of various signal processing such as short-time Fourier transforms for high-frame-rate images acquired with high-speed vision.
