Ultrasonics (spring 2017)

Ultrasonics, spring 2017

 

Lecturer: Prof. Edward Hæggström

Assistants: M.Sc. Timo Rauhala and M.Sc. Axi Holmström

Contact Axi Holmström with questions: axi.holmstrom(at)helsinki.fi

 

This class shows you what ultrasound can be used for. It is much more than baby images. We also show you the physics behind the ultrasonic interaction in both sensing and actuation applications.
