Abstract (en)
[origin: EP0953952A2] An electromagnetic radiation sensing device (20) has an n x m array (22) of detecting elements (24) (where n and m are integers greater than unity). These elements (24) are symmetrically arranged about at least one axis, so as to form at least two sub-arrays (26,28). In response to illumination by electromagnetic radiation the sub-arrays (26,28) produce output signals which are substantially equivalent in magnitude and phase. <IMAGE>
