Abstract
Оne of the key units of an optical device is a radiation receiver. At the design stage, the receiver is selected for spectral sensitivity to perform the specific research tasks. It is assumed that the spectral composition of radiation passing through the optical system of the device remains unchanged, and the receiver response is predictable and effective. With variations in the color of the radiation, due to structural changes in functional materials, a decrease in the efficiency of radiation registration by an optical device can be observed. The purpose of this work is to determine the effect of deformation and ionizing radiation on the color characteristics of the rays passing through the LiF crystal, which acts as light filter. For the first time it has been found that with increasing of residual deformation in LiF samples, the spectral curves tl(l), color coordinates and brightness of a basic color of radiation as well change non-monotonously. In the deformation interval 0,155...0,8 %, increase in deformation leads to the reduction of these parameters for about 1,5 times, but after passing the critical point of 0,8 % (transition from primary to secondary sliding planes when moving dislocations), the situation changes to the opposite – increasing deformations to 3,3 % returns the specified characteristics to the original level. At the same time, the change in ε in the interval 0,155...0,8 % does not affect the color of the radiation passing through the crystal. The indicated effect of the reversible displacement of the quantitative optical characteristics of radiation with the invariability of qualitative ones, it's may appear to be of interest for applied optics (lighting engineering, colorimetry, photometry) and physics of devices, elements and systems.
