Diffuse light source with variable radiance for calibration of precise digital video systems

This study provides insights into a new scheme for measuring radiant characteristics and calibration of precise digital video systems, based on the original diffuse light source with variable radiance. This source provides better metrological characteristics of the calibration of new generation of digital spacebased video systems of high definition. We also analyze the types of the inner surface coating of the source. Different variants of light sources were reviewed and just miniature tungsten halogen lamps

The algorithm of determining the source of ionizing radiation location at the study of the object with a difficult geometry

This paper considers the problem of detecting the specific place of the source of ionizing radiation (SIR) location when studying the object with a difficult geometry utilizing the system of dosimetria situation visualization. Specifically, we propose the verification method of the source orientation through а mathematical vehicle and develop the algorithm of determining the distance from а detector to the source.
