This project aims to develop terahertz imaging systems based on quantum cascade lasers suitable for characterisation of skin, with major implications for early skin cancer detection. Despite advances in treatment regimes, the most significant predictor of skin cancer survivability remains early detection. The project’s approach uses the semiconductor laser in the optical-feedback interferometer configuration, and is designed to afford significant advantages over conventional terahertz imaging platforms. The project plans to explore new semiconductor physics of a quantum cascade laser under optical feedback, engineer the semiconductor laser-based platform for medical diagnostic applications, and develop supporting numerical techniques.

该项目旨在开发基于量子级联激光器的太赫兹成像系统，适用于皮肤表征，对早期皮肤癌检测具有重要意义。尽管治疗方案取得了进展，但皮肤癌存活率的最重要预测因素仍然是早期发现。该项目的方法在光反馈干涉仪配置中使用半导体激光器，并且旨在提供比传统太赫兹成像平台更大的优势。该项目计划在光反馈下探索量子级联激光器的新半导体物理，设计基于半导体激光器的医疗诊断应用平台，并开发支持数字技术。
