Abstract: An area measurement system employing a one dimensional photosensitive array, with inter-element spacing of & = 3cm is described. A mathematical formulation of perturbation applied to length & area measurement and contour detection is reviewed and presented. A description of the proposed experimental system is given. An area measurement error is defined and applied to the projected object images. It is found that static images (no perturbation) produces considerable error. It is then found that the applilcation of a one dimensional sinusoidal image perturbation greatly reduces the area measurement error, while triangular image perturbation is optimum and theoretically results in zero error. Some practical applications of the system are suggested.
