Abstract
A method for the optimization of illumination in line-scan camera systems i s proposed. By using this method it is possible to calculate the optimal po sitions and luminous intensities of the light sources to obtain the desired illuminance at a surface. The proposed method is especially suitable fur p roducing uniform illumination on a line. The method can be used with severa l types of light source, because experimental general models can be used fo r the lamps. The method is based on the regularized least squares optimizat ion. The performance of the method is evaluated by comparing the calculated and measured illuminances before: and after the optimization.
