粉体製造プロセスにおけるディジタルホログラフィを用いた微粒子測定

抄録

In this paper, we explain the principles of holography to the main problems and solutions to facilitate the introduction of holographic particle measurement into the powder production process. Using the Jetson Orin Nano (NVIDIA), one of the single-board computers with GPU (Graphics Processing Unit), we develop a module that streamlines the optical system for seamless integration into the process. We are also clarifying the issues that need to be addressed in the module design. Finally, we describe the characteristics of the reconstructed particles measured by real-time holographic particle measurement using the module.
