3D Microwave Imaging for Medical and Security Applications

The use of microwaves for imaging applications is currently of much research interest particularly in the areas of security imaging and medical imaging. Microwaves have been shown to be able to image objects concealed beneath clothing and recent research work has indicated that microwaves could offer a new low cost non-ionising technique for the detection and imaging of breast cancer tumours. Traditional intensity only measurements have only been able to provide 2D images of objects. This work describes how our indirect holographic approach can be used to reconstruct 3D images of objects from a single scalar 2D holographic intensity pattern
