CLOUD FORM IDENTIFIER Russian patent published in 2008 - IPC G01J3/06 

FIELD: physics.

SUBSTANCE: invention concerns devices identifying cloud form and quantity on the basis of spatio-temporal structure of its infrared emission. The cloud form identifier includes radiometre, scanning system, data registration and processing system (registration unit). Scanning system is a mirror rotating around optical axis along a cone generating line, with variable angle between the optic axis and mirror surface (zenith angle), and projecting a hemispheric configurable-resolution image of cloud emission field onto the radiometre receiver. The mirror's operation procedure is as follows: full circular scanning by azimuth angle is performed at a given zenith angle, the zenith angle is being changed gradually, and full circular scanning by azimuth angle is performed for each value of the zenith angle.

EFFECT: increased operation speed and possibility to register hemispheric configurable-resolution image of cloud emission field for cloud identification on the basis of the space pattern.
