Multispectral observation for thermal object

Multispectral thermal imaging considerably facilitates observation and identification of thermal objects. The transition from separate imaging to the complex imaging in various ranges of spectrum raises efficiency of this process. Under the word `complex' authors mean the image formed from the several `primary' images, received in several spectral zones. The variants of multispectral devices design, arising problems and ways for their overcoming are considered in this paper. A number of original units for image primary processing is proposed. It is offered to use a vidicon TV camera and a pyrovidicon IR camera as a base for the complex imaging system. Authors have opinion that application of these cameras is the most expedient at the moment.
