SUPPLEMENTARY NOTES
ABSTRACTThis report results from a contract tasking of the Ioffe Institute as follows: Historically Russian holographic research laboratories developed many unique materials having no analogs in other countries. This effort leverages that expertise and investigates two aspects related to correction of distortion of laser communications signals: 1. Development of the technique for compensation of atmospheric distortions in laser communication systems by means of dynamic holograms. We expect that depending upon the chosen holographic medium the following operational characteristics are attainable: Duration of a write/read/erase cycle -1.0 msecond; Quality of correction -80%; Improvement of the signal to noise ratio -90%. The device will be automatic, real-time and reliable. 2. Development of a new holographic material based on self-developing dichromated colloids, for recording of stationary volume holograms. This task will include measurement of the optical effects caused by photoinduced structural changes and hopes to achieve a resolution of up to 5000 l/mm and sensitivity down to 100 mJ/cm2.
SUBJECT TERMS
Project goalsThe following are the two major subtasks of the proposed project: 1. Development of the technique for compensation of distortions in laser beam wave front induced by inhomogeneous media, by means of dynamic holograms. 2. Development of a new holographic material on the base of dichromated colloids, for recording of stationary volume holograms 3 CONTENTS
