Revolutionary threads could disrupt one of the world’s oldest industries and keep nearly 50,000 jobs in the U.S. over the next ten years. They will be able to monitor vital signs, convert light to electricity, and “cloak” soldiers on the battlefield.
Smart Fabrics. Shirts that can monitor blood pressure, jackets that can store and convert thermal energy, window shades and tents that harvest solar energy, dresses that change color at the push of a button, and self-drying shoes are part of a new photonics initiative with both military and commercial applications. This new technology can be used as threads woven into textiles which could conceivably conduct electricity, sense the temperature and body functions, communicate with the internet, and detect threats and report injuries to soldiers on the battlefield.
A University of Central Florida scientist is playing a critical role in shaping a $317 million U.S. Department of Defense program that could expand the function of clothing to include monitoring our health, sensing the environment, and harvesting energy.
The process of creating a fiber capable of functioning as a fully integrated and networked system will essentially meld together a diversity of materials not usually associated with optical fibers, such as metals and semiconductor materials, along with the more traditional glasses and plastics. These ‘multimaterial’ fibers can realize the functions provided in electronic devices in a low-cost package slightly thicker than a strand of hair.

This course introduces the students to recent advances in optics & photonics. Students read selected articles in technical magazines and make seminar-like presentations to the class. Ethical issues associated with research and data management are discussed and addressed in students’ presentations. Students are introduced to techniques of effective communication, as appropriate to the discipline.
This course introduces the basic principles of two- and three-dimensional imaging systems. It includes the mathematics of image formation as a linear system and introduces point spread function, transfer function, resolution, and restoration. Objects such as microscopes, telescopes, and copiers operating in the gazing and scanning configurations are modeled and their resolution assessed. Interferometric imaging systems and their applications in metrology are described.
