Spectral filtration of images in the IR spectral region with use of phenomenon of total internal reflection and multibeam interference

摘要

Parameter calculations were carried out for two types of filtering devices in one of which the phenomenon of the total internal reflection was used and in the other the multibeam interference was used for the optical radiation filtering. It is expected that these devices may be suitable for imagery of objects in the given narrow spectral bands - spectral imaging (SI).
