Abstract
FIELD: air optics. SUBSTANCE: method involves detection of angular velocity of sample moving air or space object, recording N sequences of object pictures which period is less than time interval of constant state of air and interval between sequences is greater than time interval of constant state of air. These sequences are converted to spectral pictures which combined in pairs and are accumulated on single photographic sheet. Picture intensity in center is compared to threshold. Said procedure is repeated for different intervals between object shots until threshold is not reached. Before all operations maximal angular object size Δθis detected and telescope aperture is set to diameter D' according to equation D′<1,22λ/Δθ... EFFECT: increased precision. 2 dwg
