Looking into Hidden Worlds:
Intro to Subsurface Sensing and Imaging Systems
Engineers are often faced with the problem of sensing and imaging objects
that are
hidden under a surface. For example, detecting tumors using laser scanning
microscopy, locating underground mines using radio waves, imaging infants using
ultrasound, detecting cracks in machine parts and bridges, and medical imaging
by xray
radiography, magnetic resonance imaging (MRI), and computer assisted
tomography (CAT). This course will introduce the student to the basics of subsurface
sensing and imaging:
• Properties of probes such as opticalbeams, x-rays, ultrasonic waves,
and electromagnetic waves.
•
How the probes interact with media – transmission, reflection, scattering,
diffusion
• Sensors for detecting subsurface signals
• Extracting information from subsurface signals using multi-view tomography
(MVT), Localized probing and mosaicing
(LPM), and multi-spectral discrimination (MSD).
