Hi,
As a part of our outreach activities, IIT (BHU) SPIE & OPTICA STUDENT CHAPTERS in association with the Dept of Physics, are organizing two talks in sequence, and details are
Date: 21 October 2024 , at 4: 45 PM
Venue: Seminar Hall, Physics,IIT (BHU)
You are cordially invited to this seminar.
Title:
High-speed 3D / ultrafast imaging by holography
Speaker
Yasuhiro Awatsuji, Faculty of Electrical Engineering and Electronics,
Kyoto Institute of Technology
Abstract:
We have studied two techniques using holography; high-speed
three-dimensional (3D) imaging and ultrafast movie recording.
High-speed 3D imaging is achieved using parallel phase-shift digital
holography. Parallel phase-shift digital holography has the ability
to record the complex amplitude of light from an object in a single
shot.Parallel phase-shift digital holography is described and
high-speed moving images obtained by this technique are presented.
Ultrafast movie recording is achieved by light-in-flight recording by
holography. Light-in-flight recording by holography can record
slow-motion movies of light propagation. Also, light-in-flight
recording by holography is described and ultrafast movies obtained by
these techniques are presented.
[short biography]
Yasuhiro Awatsuji received the BE, ME and DE degrees in applied
physics from Osaka University, in 1992, 1994 and 1997, respectively.
He has been a Professor with the Faculty of Electrical Engineering and
Electronics, Kyoto Institute of Technology since 2014. His research
interests are in the area of information optics with emphasis on
holography. He is also interested in the area of 3D display, 3D
measurement, quantitative phase imaging, microscopy, visualization of
invisible objects, high-speed imaging, and ultrafast imaging. He is a
senior member of Optica and SPIE.
