Abstract
The term ‘tomography’ refers to the general class of devices and procedures for producing two-dimensional cross-sectional images of a three-dimensional object. Therefore, tomographic imaging is a technique which is capable of revealing internal structures through the use of ionizing or non-ionizing penetrating waves in a non-invasive and non-destructive manner. Ionizing sources include X-ray, while electrical techniques and microwaves belong to the class of non-ionizing radiation. With the safety advantage of non-ionizing radiation, the use of soft-field sensors for food and beverages imaging has been a subject of interest for several decades, realizing the potential and challenges, and exploring several techniques. This chapter discusses different types of sensors and electronics needed to acquire tomographic signals, with emphasis given to emerging modalities like electrical impedance systems and ultra wide band sensing.
