Terahertz Frequency Imaging Systems for Biomedical & other Applications

Objective

Compact terahertz (THz) pulsed imaging (TPI) systems will be realized using short (fs) near infra red (NIR) pulses which impinge on semiconductor (and other) "photoconverters". NIR lasers will be developed with average power exceeding 2W, and an overall footprint less than 50cm x 70cm. Photoconverter efficiencies will be increased by at least 100 X over present levels. Developments in detector and image acquisition techniques will enhance signal: noise by at least 10 X. A complete, compact, TPI system will be constructed with an average output power of at least 200-300 microwatt. This will deliver images of samples up to 5cm x 5cm, at a rate of 2-3 per minute, containing information from 1-10THz. The final system will encompass developments necessary to enhance its use in medical work. To achieve this, systematic investigation of the use of TPI systems in medicine will be made, involving comparisons with other imaging technologies; new imaging software will be developed. THz imaging, using the mixing of cwNIR lasers, will also be investigated. A compact CW imaging system will be realized. Imaging at 1THz will be demonstrated and comparisons made with TPI system performance
