Speckle statistics
Presently, the group is in involved in the Innovation Consortium, CINO, with the aim of establishing a suite of miniaturized optical sensors, primarily for two Danish companies. Besides, the group is participating in a Danish National Advanced Technology Foundation project in which an optically based miniaturized cursor control system is being developed focused on being applied within cellular phones, mini pc-laptops etc.
Ultra-violet LED light systems
Newly developed ultra-violet LED light sources have a potential for disinfection and sterilization. Especially applications within food stuff and the medical area are of prospective interest. Their power at germicidal wavelengths and smallness are outstanding compared to common UV-light sources. The Optical Sensor Technology Group at DTU Fotonik carries out research and innovation with focus on applications of this new technology in the medical field.
LIDAR systems
Development of laser anemometers for wind speed determination has been an ongoing research field in the group for more than a decade. The group has in close collaboration with OPDI Technologies recently demonstrated a first all semiconductor LIDAR version. This system is now being exploited commercially.
Nonlinear Optics
The use of Sum Frequency Generation, tapered diode lasers and solid state enhancement cavities is investigated for efficient generation of visible and UV light. Tailoring the nonlinear interaction allows us to demonstrate a novel approach for efficient up-conversion of 2-dimensional images.
