Abstract : The effectiveness of using a bismuth silicon oxide (BSO) electro optic crystal to holographically correct synthetic-aperture aberrations is investigated. A theoretical analysis of hologram formation in electro optic crystals was performed. Experiments were then conducted to determine the diffraction efficiency and hologram erasure rate characteristics for the BSO crystal. The BSO crystal successfully performed real time aberration correction of a single lens optical system; but due to the experimental synthetic aperture optical design, it was impossible for the crystal to correct the synthetic aperture aberrations.
