Fiber-optic equipment based on quartz and silicate optical fibers hits the market of communications and telecommunications. Further development of fiber optical transmission systems helps to extend the scope of fiber optic systems for information delivery over the region of =2-25m. It is just the medium IR spectral range that holds a fundamental niche of information space, being the carrier of molecular and thermal information, i.e. information about composition and temperature of the subject, simultaneously. Carriers of original molecular and thermal “imprints” are solid, liquid and gaseous subjects themselves, oscillations of atomic bonds in these subjects being in the information niche of medium IR range. Reception of such information allows to investigate the majority of chemical and part of physical processes in real time and makes possible control over these processes at the moment of their performance. Similar comprehensive approach can make basic designation of IR wave guide systems for medium IR range.
No single universal material for IR medium spectral range has been found yet; fluoride, chalcogenide, crystalline and hollow wave guides are being developed enable IR fiber system development. However, each of these wave guides is capable to solve tasks only in limited part of the medium IR range. The new stage in research and development of IR fiber materials requires transition to polyfiber IR systems consisting of several types of IR wave guides, whose spectral transmittance range enables their application for the whole medium IR spectral range. Various combinations of integrated optical fibers depend upon combinatorics of IR polyfiber systems considering the type of material, wave guide structure, purpose, variety of analyzed subjects. With this in mind, reasonable “architecture” of multi-channel polyfiber system is generated capable to receive, process and analyze simultaneously several types of information both of chemical, and physical nature in coordinates “molecular composition - temperature – time”.
Purpose of the Project is to research, develop and create polyfiber receive-transmission modules and systems for medium IR range, which consist of various types of IR wave guides and are capable to receive, transmit and process in real time several types of molecular and thermal information from solid, liquid and gaseous subjects of ecological, industrial and biological-medical purpose, including IR polyfiber systems for monitoring toxic gases in chemical and radiochemical laboratories and plants; for remote monitoring production technologies of drying inorganic materials, organic substances and woven fabric; for control and process monitoring of regeneration and controllable modifying of injured intervertebral tissues.
Specialists of ARICT and NSC GPI of RAS carry out research in technology of infrared fiber materials, such as: fluoride optical fibers for instrument making, and halogenide crystalline optical fibers and certain sensors for infrared range, which can serve the basis for implementation of large scale research into basic problems of IR fiber system development.
While accomplishing the Project the researches are to be carried out solving the following basic problems:
1. Develop combinatorics of polyfiber multichannel systems for taking molecular and thermal imprints in real time.
2. Research and develop polyfiber optical modules able to emit, transmit and receive information for multichannel systems for IR medium range: broadband IR polyfiber radiation source; self focusing and collimation fiber optic and gradient optical modules for IR image transmission; new types of IR fiber sensors and multi-channel optical modules on their basis for definition of molecular composition and temperature of fluids, biotissues and solid bodies.
3. Develop multipurpose polyfiber systems for delivery and processing of molecular and thermal information of exploratory, industrial and medical purpose, including systems for:
- Monitoring aggressive, toxic and explosive gases and vapors at operator’s position in chemical and radiochemical laboratories and plants;
- Remote control of production processes of drying inorganic materials, organic substances and for drying fabric in textile manufacture;
- Biomedical laser complex for implementation of a new method of regeneration and controllable modification of defective vertebral column tissues and injured intervertebral disks (scoliosis, etc.).
Expected results and application
During Project implementation combinatorics of optical fibers different in the type of material, structure and functional purpose, which can be integrated in polyfiber multichannel systems for detection of infrared (molecular and thermal) radiation in a wide spectral range will be developed. Receiving and transmitting polyfiber optical modules for reception, transmission and processing of molecular and thermal information will be offered and implemented, and universal polyfiber systems operating in real time for medium IR range for biomedical, ecological and industrial purpose will be designed.
Realization of the Project will make it possible:
- To develop a broadband source with a polyfiber output for medium IR spectral range;
- To manufacture self focusing and collimation fiber optic and gradient optical modules for delivery of IR image within = 3 15m;
- To develop unique polyfiber optical modules for definition of molecular composition and temperature of fluids, biotissues and solid bodies;
- To develop a universal polyfiber system for monitoring aggressive, toxic and explosive gases and vapors for chemical and radiochemical laboratories and plants;
- To develop fiber optic system for remote control of drying procedure intended for automatic control of drying chambers from measuring parameters “humidity-temperature”;
- To create a prototype of fiber optic biomedical laser complex for regeneration and controllable modification of injured tissues of vertebral column and defective intervertebral disks (scoliosis, etc.).
Practical and Commercial Value of the Project consists in development of several types of polyfiber multichannel systems of IR range which are highly requested in medicine, environmental protection, industrial technologies and instrument making. Fiber optic system for minimal invasive treatment of intervertebral disks will be used for creation of laser medical complex. The system of remote monitoring of water content and temperature of fabric, which is developed with reference to drying chambers of textile manufacture, can be used in technological procedure of drying during production of inorganic and organic substances, medicines and in food industry. Polyfiber systems of monitoring toxic gases should become a basis of portable devices on operator’s position of chemical and radiochemical laboratories. Development of polyfiber systems for IR range will speed up creation of new commercial products and will promote formation of the market of science and hi-tech products.
Highly skilled specialists in the field of chemistry, processing technique and physics, engaged in manufacture of nuclear weapon and scientists of the Russian Academy of Sciences are to be involved in the Project. Experts of ARICT to be involved in the Project during several years have carried out researches on synthesis of oxides and fluorides for nuclear technologies and studied several types of materials for nuclear engineering. NSC GPI of RAS experts have accumulated much experience in the field of IR fiber materials, wave guide optics and its application. The Project will give the opportunity to scientists and experts involved in weapon production to redirect their abilities to peaceful purposes, especially in the field of environmental protection and medicine, promote integration of Russian scientists into the international science community and, also, to reinforce the transition to market-based economy responsive to civil needs.

Technical Approach and Methodology
Project implementation is based on uniting optical-physical, material science and circuit engineering approaches. Combinatorics of polyfiber systems, consisting of several types of infrared optical fibers different in wave guide material (halogenide, chalcogenide fluoride, quartz) and its structure (two-layer, gradient, hollow, etc.) is being developed. Number of used IR optical fibers is not limited. All these fibers completely overlap IR spectral range (125 m), however each fiber channel is used for receipt and transmission of molecular and/or thermal information in the limited, inpidual part of IR spectra. All fiber channels receive and analyze information simultaneously, in real time, i.e. “on-line”. When taking molecular imprints, and in order to implement possibilities of reflective and absorption IR spectroscopy, unique optical modules, which have no analogues, will be used, namely: broadband, IR sources with polyfiber output, gradient lenses for medium IR spectral range, and, also, new, non-traditional types of optical fibers. Universal approach will be used to develop multipurpose polyfiber systems of different type. Modern optical-physical and physical-chemical methods of investigations, as well as electronic design, will be applied in the course of project implementation.
