Ultrasonics (spring 2019)

Ultrasonics, spring 2019

 

Lecturer: Prof. Edward Hæggström

Assistant: 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.

 

Course duration: 15.1.2019-8.5.2019

Lectures: Tue 12.15-14.00, D116, Physicum, and Wed 12.15-14.00, D117, Physicum

Exercises/Demos: Wed 14.15-16.00, CK107 Exactum
