Research Abstract

This research aimed to develop a new optical imaging method called ultrafast optical interference tomography which images ultrafast phenomena causing refractive index modulation in transparent materials. As a demonstration we constructed an auto-measurement system and we measured propagating ultrasonic pulses in a glass with 150 nm spatial- and 1 ps temporal- resolutions. We also tried to develop the method imaging three dimensional velocity and refractive index distributions in living cells.
