A heliostat is a device consisting essentially of an animated mirror of a certain rotational motion and that serves to direct the rays of the Sun in a certain direction, in spite of the movement of the Earth with respect to the Sun.
The heliostat is used in various applications for different reasons:
- Astronomy. In astronomy this mechanism is used to observe the Sun without having to vary the orientation of the apparatus of observation
- Geodesy. In the field of geodesy the heliostat is used to transmit luminous signals at long distance
- Solar energy. In the solar thermal power plants of the heliostat it is used to concentrate the rays of the Sun in a certain point or zone where the solar collectors are.
