Abstract:
A vectorial photosensor comprising three or more photosensitive means, placed on respectively different surfaces of a polyhedron, that transform incident energy into electrical signals, and electronic means which acquire and process the electrical signals originated in the sensing means to obtain the direction of the incident energy, characterized in that its electronic means acquires and process the electrical signals originated at least in three sensitive means, placed not parallel in space, and obtains the vector p, which expresses the energy flux density of the incident energy, through the equation [s1s2s3]=[e1&it;xe1&it;ye1&it;ze2&it;xe2&it;ye2&it;ze3&it;xe3&it;ye3&it;z]&CenterDot;[pxpypz]where:s1, s2, s3 are the signals generated by three sensitive means; e1x, e1y, e1z, . . . , e3x, e3y, e3z are the components of the vectorial responsivities of, respectively, each one of this sensitive means, that constitute elements of the vectorial responsivity matrix; and Px, py, pz are the components of the vector p that expresses the energy flux density of the incident energy.
