This thesis presents the development of a measurement system, based on Opto- Thermal Transient Emission Radiometry (OTTER), for studying the static and dynamic properties of human axillar skin in-vivo in this project. OTTER has been well known as a non-invasive hydration sensitive measurement technique, however, due to the restriction of infra-red laser and measurement optics, the bench-top apparatus restricts the skin measurements only on volar forearms and hands. Also, the data processing programs are getting obsolete and isolated from the measurement system, which cause most of the inconvenience of the post processing to reveal skin properties from OTTER measurements. Therefore, the main role of this project is to develop OTTER into an automatic and complete measurements system, including the portable probe, data acquisition and real-time analysis, To achieve the aim of this project, the new opto-thermal measurement system needed to be developed and optimized as follows: 1. Development of a mobile measurement head suitable for any skin site all over the human body, using fibres to deliver laser pulses. 2. Mathematical models development to improve data analysis speed and accuracy by optimizing and implementing more algorithms for the purpose of real-time analysis.
