Claim Text:
1. An optical device for sensing incident light that is indicative of a signal, comprising: a plurality of sensors arranged in a substantially co-planar arrangement configured to generate photo-signals; a first group of the plurality of sensors being configured to be exposed to the incident light; a first center of gravity region of the first group of the plurality of sensors; a second group of the plurality of sensors being configured to be shielded from the incident light; a second center of gravity region of the second group of the plurality of sensors, wherein the first and second center of gravity regions are substantially overlapping such that disturbances created by a time varying field on the first and second groups of the plurality of sensors are substantially similar in magnitude; and a circuit configured to determine an indication of the signal, wherein the circuit has an output that is substantially independent from the disturbances created by the time varying field.
