Computational Optical Sensing and Processing Laboratory
The main research challenge of our laboratory is to derive precise abstract information or decisions from large complex noisy topological data sets captured by one or multiple optical sensors. We apply special optical arrangements such as different holographic setups and fluorescent illuminations for microscopic imaging, or multi-spectral camera-based patient monitoring systems or wide-angle multi-camera systems in monitoring. The heavy computational load is handled by many-core processor arrays, such as GPUs in desktop applications or embedded low-power systems.
Main Research Areas
- Design and application of the Digital Holographic Microscopes (DHM);
- Combination of fluorescent and digital holographic microscopy;
- Automatic monitoring, classification, counting of microbiological organisms;
- Visual remote aircraft detector sensor for UAVs;
- Visual navigation for UAVs;
- Photoplethysmography;
- Infant monitoring (circadian monitoring, pain monitoring);
- Design and programming of mixed signal focal-plane sensor-processor systems.
Main Achievements
We have developed a liquid analysis devices based on digital holographic microscopy (Holodetect microscopes), which are capable of automated analysis of various liquid samples in industrial or laboratory environment in a flow-through system. The equipment is used by HUN-REN SZTAKI's utilization company, Holodetect Instruments Kft.
Together with HUN-REN SZTAKI System and Control Theory Research Laboratory, we successfully demonstrated the collision avoidance of two unmanned robot aircraft on a visual basis with on-board sensing and calculation. We have also developed several elements of visual navigation.
We have developed a camera-based device for measuring pulse and respiration signals on a non-contact way, as well as for continuous monitoring, sleep-wake cycles, and pain levels, which is currently being tested in the premature intensive care unit of Semmelweis University.
