Heterodyne interferometer for absolute amplitude vibration measurements with femtometer sensitivity
Leirset, Erlend; Engan, Helge Emil; Aksnes, Astrid (Journal article; Peer reviewed, 2013)A heterodyne interferometer for highly sensitive vibration measurements in the range 100kHz − 1.3GHz is presented. The interferometer measures absolute amplitude and phase. The signal processing of the setup is analyzed ... -
Optical Measurements of Picovibrations on Capacitive Micromachined Ultrasonic Transducers
Åldstedt, Mats Marhaug (Master thesis, 2010)A research group at the Norwegian University of Science and Technology plan to integrate Capacitive Micromachined Ultrasonic Transducers (CMUTs) in a probe which can be used to image human blood vessels from the inside. ... -
Photonic crystal light emitting diode
Leirset, Erlend (Master thesis, 2010)This master's thesis describe electromagnetic simulations of a gallium antimonide (GaSb) light emitting diode, LED. A problem for such devices is that most of the generated light is reflected from the surface due to total ...
