16. Digital holographic reconstructions of ultrasound from laser vibrometry recordings
Sammanfattning : If sound and noise from an engine, say a lawn mower, is to be reduced, it is of advantage to know from which part of the machine the noise is coming. An interesting medical application for localization of sound sources is optoacoustic imaging of tissue. LÄS MER
17. Sound source localization from laser vibrometry recordings
Sammanfattning : Acoustic holography deals with a typical inverse problem, to obtain the unknown from something that is known. From measurements of sound, most often using microphone arrays, reconstructions of the sound field are made in an attempt to find out what causes the sound. LÄS MER
18. On-line shape inspection using a projected fringe pattern
Sammanfattning : A stereo camera system together with a single projected fringe pattern and one image recording is used to measure 3D-shape. The idea is to make the measurement quick enough to be able to use the method when testing quality on-line in manufacturing industry. For this to be possible the digital master (e.g. LÄS MER
19. Shape and surface characterization using diffused light
Sammanfattning : Diffuse reflection from various surfaces have been studied using several different methods in order to draw conclusions about the surfaces. First of all the aim was to perform fast and accurate shape measurements of molded steel objects on-line in a production system. LÄS MER
20. An electronic speckle photography system for in plane deformation measurements
Sammanfattning : .... LÄS MER
