<p><P>PROBLEM TO BE SOLVED: To provide a three-dimensional direction detecting device. <P>SOLUTION: This three-dimensional direction detecting device includes an electromagnetic radiation source and a sensing module. The electromagnetic radiation source generates electromagnetic radiations. The sensing module has a base seat and a plurality of sensing elements. The base seat has surfaces positioned on a plurality of different planes. The plurality of sensing elements are installed on the surfaces of the base seat and receive different radiation energies generated by the electromagnetic radiations at different spatial angles from the electromagnetic radiation source. Thus, the sensing elements respectively receive the different radiation energies from different spatial direction angles generated by the electromagnetic radiation source relative to the sensing elements, so that the value of a spatial direction angle of the electromagnetic radiation source relative to the sensing module is obtained, according to the magnitude relation of the radiation energies received by the sensing module. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
