Optimal Perturbation Signal Waveform for Sensing Arrays

The optimal solution of perturbation signal waveform used to linearize the nonlinear transfer characteristic of the receptor array for an image sensing is sought through approximation. A completely linearized characteristic is obtained for the one-dimensional square-element receptor array without dead space by introducing this optimal perturbation signal to the system. Therefore, a zero sensing error is achieved. The result is extended to linearize one-dimensional receptor arrays having specific dead space and two-dimensional receptor arrays.
