Optical Access Schemes for High Speed and Spatial Resolution Optical Absorption Tomography in Energy Engineering

Abstract: Stylianos-Alexios Tsekenis received the BEng and EngD degrees in electrical and electronic engineering from the University of Manchester, UK in 2009 and 2013 respectively. He received the Pg.Dip degree in Enterprise management from Manchester Business School in 2011. He has held posts at Intel Corporation, Royal Dutch Shell plc. and Blaupunkt GmbH, developing instrumentation systems that are now in worldwide use. He has provided technology and be-spoke design consultancy services to the events and motorsport i… Show more

“…To overcome this limitation, we recently introduced the concept of solid-state beam deflectors to realize tomographic reconstruction with high temporal and spatial resolution. The laser beam can be deflected through an angle of 216 mrad at a repetition rate of 90 kHz using an electro-optic deflector [15]. Furthermore, stationary TDLAS tomographic sensors have been designed with multi-photodiode arrays [16,17] or fiber optics [8], in which the spatial resolution is improved by packing around the imaging space the optics for more beams.…”

“…Although more spatial samples can be obtained by the above sensors, the relatively low-speed mechanical scan of the laser beams can hardly reveal the dynamics of the target flow. Some attempts have been made by increasing the laser scanning speed, for example, introducing high-speed galvo mirrors and electro-optic beam deflectors [34]. However, the beam-scan strategy, limited by its nature of asynchronous sampling of the laser beams, is unable to capture the dynamic feature of the target flows.…”
