Abstract
Typical sources of electronics exposure in space are the high level ionizing radiation such as the Van Allen radiation belt, cosmic radiation for spacecraft and high altitude aircraft. It causes the major problem for airspace operations and space mission. Contemporary visual CCD cameras, CMOS devises, image optical sensors are extremely vulnerable to high level ionized radiation. Radiation hardening technology for contemporary electronic devices such as image sensors and image cameras causes the loss of resolution and is expensive. Using vector-tensor algorithm and theory of self-coupling electromagnetic waves in crystal symmetry 23 we demonstrated optimization of real time image procession. The results of theory were applied to doped bismuth titanium oxide crystal which exhibits electro-optical and photorefractive effect and is not vulnerable for high level X-Ray and 2x107 rad gamma radiation exposure. Under the same level radiation exposure CMOS sensor was damaged. Application potential of doped bismuth titanium oxide crystal image sensor was discussed for nondestructive, non-non-contact, in situ evaluation of the major parts of engineering constructions in space.
