<p>A method and apparatus for receiving radiant energy is provided having a linear sensitivity to the angle of arrival of the radiant energy with that linearity relatively unaffected by wavelength and polarization variations in the radiant energy. An optical fiber is provided having a receiving end disposed to receive radiant energy and also having a transmitting end. A diffusing surface for receiving radiant energy is disposed on the receiving end of the optical fiber. A detector receives radiant energy from the transmitting end of the optical fiber.</p> |
