Abstract
Apparatus for seeking and following a luminous zone, such as the sun, comprises an element angularly movable about mutually perpendicular axes. The element carries photoelectric transducers facing in different directions and which control servomotors for positioning the element to face the luminous zone in accordance with differential signals produced by the transducers.
Claims5
Apparatus for seeking a luminous zone, comprising an angularly movable element, photoelectric transducer means, mounted to said movable element, for generating signals for orientating the element towards the luminous zone, said transducer means comprising at least two first transducers facing in different directions and symmetrically disposed about a plane containing the axis of angular movement of the element, said first transducers having excitation surfaces inclined toward said plane, and servomotor means for moving the element about said axis, said servomotor means being controlled by the signals generated by the transducers.
