Project summary

Objectives of the Project
1. Theoretical and experimental investigation of optical superradiance and transient effects in the waveguiding media and extended crystals doped by rare-earth ions group.
2. Realization of experimental setup for the observation of photon echo using fiber-optic delay line.
3. The development of construction principles for fiber-optic image processor with read-out from hard carriers.
4. Realization of robust fiber-optic actuator for reading out and subsequent processing of images with the use of fiber-optic processor.

Technical approach and methodology

Fiber-optic assembly will be developed and fabricated to read out images from paper where radiation is directed to paper by optical fiber and is received by same or other fiber after the reflection from it. With that, image area is scanned mechanically. It seems reasonable to use for image processing a fiber-optic setup because the absence of electronic analog to digital converter is sufficiently rising the rate of processing and flexibility of fiber interconnections makes possible its conjugation with future optical computers. The central place among approaches used in this project is occupied by application of optical transient effects to image processing. In that context, the fiber-optic setup will be constructed for the observation of photon echo and four wave mixing with femtosecond pulses in doped by rear earth’s materials and some relevant fundamental problems will be solved. They enclose the physics of transient effects in waveguiding and extended media, and, also, application of optical superradiance to increase the efficiency of processor operation. In particular, the triggered superradiance will be experimentally and theoretically treated as a special form of photon echo with total collective radiate relaxation of the stored in atomic system excitation.

Expected Results

The fiber-optic system for reading: and processing: of images from paper will be constructed using principles of artificial intellect as a result of the project realization. The fundamental problems emerging under the construction of such system are to be solved. The obtained results can be used in future for solution of more complicated problems, for instance, concerning analysis and synthesis of moving volume images.

Potential Role of Foreign Partners

We offer to foreign partners to use the results obtained under project and participation in the investigations. The designers of optical computers for the use of can reveal the special interest developed under the project devices as peripheral. The potential partners are all designers and users of automated image reading and processing systems, in particular for robotics.
