Recording infrared images on silver-halide film
1985
Recording and measurement of the parameters of transient processes (TP) that accompany radiation in the intermediate and far infrared regions involve difficulties in the choice of a sensitive receiver for recording infrared (IR) images. There are several types of radiation receivers that operate at wavelengths ~ ~ i0 Dm: phosphors with thermal quenching, magnetic films with banded domain structures, heterogeneous ferromagnetic systems with ordered magnetic particles, ionization-type semiconductor systems, and others. However, the need for special, often fairly complicated recording and display devices and sometimes large amounts of time for decoding recording data is a serious obstacle to the wide use of these receivers in highspeed IR photography. The absence of refractive elements makes it possible to use high-speed optical reflex cameras (for example, ZSFK-2, ZSKh-I, or "Zevs") for high-speed recording and measurement of TP parameters not only in the visible but also the IR region of the spectrum. Therefore, the use of existing serially produced Silver-halide photographic materials to study TPs in the IR region is of particular interest. Below, we shall examine the theoretical premises and describe the results of experiments in the use of serially produced silver-halide films as recording media for IR images.
