Four minute nimbus detectors

摘要

(57) Abstract Four minute nimbus detectors (10) improve the precision making use of the concept of the cutoff which is formed, Iriki which possesses horizonal nearby angle of incidence by installing the baffle (28) while the designing, improve the detection response for the light (11) which, is done split the diffused reflection cavity (16) into four minute circles. To decide direction or direction and altitude the hemispherical body or vis-a-vis the illuminant where it is somewhere within the sector in sphere it is possible four minute circular detectors (10).
