responsivity of one of the sensitive means by its sensitive surface and its direction the perpendicular to such surface being incoming by the sensitive face the electrical output of each sensitive means designated s i can be expressed as the scalar product of the vectorial responsivity e i and the vector p that represents the energy flux density this invention may incorporate from three up to an undefined number n of sensitive means located each one of them on each one of the faces of a polyhedric surface constituting the transducer of the vectorial photosensor considering an orthogonal base oxyz we represent the vectorial responsivities in function of its components with respect to the base as e 1 e 1 ue89e x e 1 ue89e y e 1 ue89e z e 2 e 2 ue89e x e 2 ue89e y e 2 ue89e z e 3 e 3 ue89e x e 3 ue89e y e 3 ue89e z in an analogous way we represent the energy flux density in function of its components with respect to the base as p p x p y p z in this way we represent the signals generated by the sensitive means as s i e ix e iy e iz t u00b7 p x p y p z that is to say s i e ix e iy e iz u00b7 p x p y p z the equation that describes the physical implementation of this invention is s 1 s 2 s 3 e 1 ue89e x e 1 ue89e y e 1 ue89e z e 2 ue89e x e 2 ue89e y e 2 ue89e z e 3 ue89e x.
