FIELD: physics.
SUBSTANCE: panoramic sensor of angular coordinate of light checkpoint includes multielement receiver of optical radiation consisting of at least three elemental photo receivers, and signal processing device for defining angular coordinate of checkpoint. Elemental photo receivers are set in circle at regular pace. Number of lit elemental photo receivers within a single unit does not depend on the direction of light checkpoint at a given plane in the sensor coordinate system. Angular coordinate of checkpoint is defined either by order numbers of end elemental receivers in the lit group of photo receivers or by correlation of signal size at any two lit photo receivers, possibly adjoining ones.
EFFECT: viewing field extension for sensor angular coordinate of a light checkpoint.
