METHOD OF SPECTRAL AND ZONE PHOTOGRAPHING AND DEVICE FOR ITS REALIZATION Russian patent published in 1998 - IPC

FIELD: photographic technique. SUBSTANCE: photographic film with frame overlapping factor not less than (n-1)/n is exposed through light filters having transmission in different spectral zones installed one after another in front of focal plane of photographic camera. Light filters are mounted one after another in direction of motion of image of flight of carrier and their summary area is equal to area of frame window. As result section of terrain that was exposed in first frame through first light filter is exposed through second light filter in second frame and so on. Thus series of photographs of terrain in spectral ranges corresponding to transmission of light filters will be obtained. EFFECT: diminished photographing cycle. 2 cl, 2 dwg
