Prediction of the optical properties of ruby and leucosapphire under conditions of cosmic-plasma action

On the basis of the results obtained earlier in the experimental and theoretical investigation of radiation-optical effects in ruby and leucosapphire, methods of practical importance are developed for the computer prediction of the optical transparency of ruby and the luminescent-noise intensity from a leucosapphire lens of a spacecraft under conditions of cosmic-plasma action. The change in optical density of ruby and the level of luminescent noise from the leucosapphire lens of a spacecraft moving in interplanetary space in the course of a solar flare described by the Bailey method is calculated.
