Module Overview

This course describes the concepts behind Radiation Imaging and Remote Sensing, both in term of the various types of detectors used for radiation imaging, and their application to radiation monitoring and sensing. Both semiconductor and scintillators imaging detectors will be described, including the latest developments in silicon pixel detectors and CMOS pixellated devices. Imaging theory will also be reviewed, including Modulation Transfer Function and Detector Quantum Efficiency. The application of detectors for radiation imaging will be described, including Compton scatter telescopes, coded-aperture cameras and collimated detectors. The application of imaging will be explored in terms of remote sensing, with a particular emphasis on environmental measurements and security imaging.

Module Aims

This module will provide the student with a more detailed understanding of the operation and performance of various semiconductor and scintillator-based imaging detectors, including silicon pixel detectors, CMOS sensors, scintillators-based cameras and neutron imaging detectors. The module will explore quantitative methods for assessing imaging detector performance, and will discuss the use of imaging and remote sensing detectors for various applications, including security imaging, remote monitoring, and environmental measurements.

Learning Outcomes
After completing this module, the student will have acquired the following:

Module Specific Skills:
• An in-depth understanding of the performance and operation of a range of semiconductor and scintillation imaging detectors.
• Critical application of methods for quantitative analysis of imaging detectors and data.
• Detailed knowledge of the application of imaging and remote-sensing detectors to a variety of applications including environmental monitoring and security imaging.
