Popular Abstract
At the Department of Biomedical Engineering work has been done on micro- dispensers - micro-mechanical devices used for handling extremely small volumes of fluid, which is used in the pharmacological industry. The main part of these devices is a membrane which moves distances on the order of micrometers, and vibrates with natural modes at frequencies over 10kHz, and there was a desire to image the motion in high time-resolution. The idea was to use interferometry to measure the shape of the membrane and an interferometric set-up had been constructed to prove the concept on a stationary membrane, but the vibration modes when the membrane was in motion could not be imaged with this set-up since the vibrations were several orders of magnitude...

At the Department of Biomedical Engineering work has been done on micro- dispensers - micro-mechanical devices used for handling extremely small volumes of fluid, which is used in the pharmacological industry. The main part of these devices is a membrane which moves distances on the order of micrometers, and vibrates with natural modes at frequencies over 10kHz, and there was a desire to image the motion in high time-resolution. The idea was to use interferometry to measure the shape of the membrane and an interferometric set-up had been constructed to prove the concept on a stationary membrane, but the vibration modes when the membrane was in motion could not be imaged with this set-up since the vibrations were several orders of magnitude to fast for the camera to capture. This thesis covers the construction and optimization of a suggested set-up that might be capable of imaging the high-frequency vibration modes of such a membrane in motion, and to investigate its capacity and give recommendations for further development.
