Summary:Heliostat with a drive shaft pointing to the objective, reflection sensor and closed loop control. It comprises a reflective surface (1), capable of rotating by a primary drive (4) around a primary axis (3) pointing to the target, integral with a mobile support (2) which, in turn, is capable of turning around a secondary axis (5) perpendicular to the primary axis (3), by means of a secondary drive (6). Both drives (4) (6) are governed by a control device (8). The control system (8) together with the sensors (14) (15), of which one of them in turn contains an optical system (17), allows it to be governed in closed loop mode. The sensors detect the position of the sun on one or the other side of their respective reference planes. One of the sensors will be placed in the mobile structure (2) that supports the reflective surface (1) with the reference plane parallel to the primary axis (3). The other sensor will join solidariamente to the mobile part of the system that rotates according to the primary geometrical axis (3) with the reference plane parallel to the secondary axis (5), and receive the reflected radiation from a reflecting plane perpendicular at origin to the reflective surface (1) and parallel to the secondary axis (5).

Ambos accionamientos (4) (6) están gobernados por un dispositivo de control (8).El sistema de control (8) junto con los sensores (14) (15), de los cuales uno de ellos a su vez contiene un sistema óptico (17), permite que se gobierne en modo de lazo cerrado.Los sensores detectan la posición del sol a uno u otro lado de sus respectivos planos de referencia. Uno de los sensores se colocará en la estructura móvil (2) que soporta la superficie reflectante (1) con el plano de referencia paralelo al eje geométrico primario (3). El otro sensor se unirá solidariamente a la parte móvil del sistema que gira según el eje geométrico primario (3) con el plano de referencia paralelo al eje geométrico secundado (5), y recibirá la radiación reflejada de un plano reflectante perpendicular en origen a la superficie reflectante (1) y paralelo al eje geométrico secundario (5).
