We are aiming at the development of an inexpensive system that can shoot, record, and analyze the minute world of nano-scale. As the first step, a new visualization system was built using a household high-definition video camera (HDR-HC3) and an optical microscope with the darkfield illumination. And, we evaluate its usage in ferromagnetic nano-particles visualization of magnetic fluid, and make sure its effectiveness in it.
