A very simple sensor for the measurement of rotation angles is presented. The sensor is based on the wavelength variation observed in the focal plane of a system conceived with a diffraction grating and a lens. White light is launched in the input fiber. If the grating undergoes a rotation, the wavelength received by the output fiber is altered.
