Paper Abstract

A novel DHI technique of precise targeting of moving object in space has been made. The major advantage of this technique is automatic self-adjustment of volume adaptive supersmall (0. 12 mm) holographic grating in a new syntezed double doped photorefractive crystal of BTO. This results in the creation of 70 % diffraction efficiency adaptive holographic grating using 0.632 mm laser radiation. The targeting angle deviation of 10 radians in real time testing has been verified using low power CW He-. Ne laser at a distance of0.5 meter.
