PROJECTS

Optical Powering — design of a network of optically powered fuel level sensors for aircraft tanks. The conventional capacitance based unit is modified by incorporating an optoelectronic module placed inside the unit and optically connected to a fiber-optic transmission line. The unit is electrically isolated from the tank exterior; moreover, the sensing capacitive element has no electric contact with the internal optoelectronic module.

Fluorescence Oxygen Sensor — design of a fluorescent oxigen sensor detection system with single photon counter based on time-gated lifetime measurements. The essential advantage of the system with digital response is that with shifting the range of counts to the higher portion of linear range of the counter the relative error of measurements stochastic by origin is reduced as N^-1/2. Another advantage of the system is its optical simplicity and robustness. It contains no optical elements but a fiber-optic cable, no filters, and no spectral analyzers. No optical adjustment is required and no optical element can be detuned during operation, therefore the system can reliably operate in harsh environment with severe mechanical vibrations.

DNA Sequencing
— We have developed and manufactured a miniature DNA Sequencer capable of DNA sequencing of biological samples with an accuracy exeeding the existing commercial sequencers. Our fluorescence DNA Sequencer is a portable device for the reliable DNA sequencing of biological samples in laboratory and field conditions. Customer — NIH (National Institute of Health). Our company can also perform the following services with our device: DNA sequencing for medical and biological needs, forensic servises for the law-inforcing organisations.

Fluorescence Imaging
— Development of fluorescent imaging system for neuro-surgical microscopes with an enhanced image of fluorescing tumor tissue overlapped with the surgery operation field image visible by the surgeon’s eye throught the ocular lens. The system is based on time gating of flurescence image registered by a black-white CD camera from the visible image, the fluorescence image processing and enhancement, and following insertion of the enhanced and artificially colored image to the optical path of microscope.
