This is me!
▪ Hobby-‐Scientist as my Life work– Daily log : http://www.hirax.net– Field of the my works; ▪ Science behind our daily life▪ Science for Adults▪ To Explore various invisible world
▪ Imaging-‐science for Money– If you have any small problem and much plenty of money, then you’d better to call me!
Guinness Beer cascades invites us into here!▪ The phenomena fascinates all of us.
▪ Actually, I always drink Guinness beer when I’ve been studying OpenFOAMwith our small study group (The leader: Masami Kadonaga)
Let’s learn “Electromagnetic spectrum”
▪ Wavelength around one micro meters, and frequency 30 Tera Hertz
My Nude Picture taken with NIR Camera
▪ We can see very different world from normal visible light world!
How drink materials look like with NIR-‐eyes?
▪ Many dark/black drinks change their looks!
(into “Transparent”)
Ok. We can see inside the Guinness Cascades!
▪ I shot Guinness Cascades every Sunday morning!
(using NIR camera and sun light)

PIV (Particle Image Velocimetry)
▪ To estimate velocity distribution of nitrogen bubble motion by using Particle Image Velocimetry (PIV)
▪ “Velocity of image patterns”
▪ With ImageJ PIV plugin
×mmくらい
PIV (Particle Image Velocimetry) result
Vertical velocity (White:Up)
Horizontal velocity (White:Going outside)
