Abstract
A method of aiming a light source includes using an image-capturing device to capture a light beam pattern from the light source. Here, the light beam pattern is configured to include a plurality of contrast ratios transitioning from a first intensity region to a second intensity region. The method includes processing the contrast ratios of the light beam pattern to obtain corresponding values of the contrast ratios, transitioning from the first intensity region to the second intensity region, where the corresponding values are logarithmic values, which in turn generate a related response curve. Finally, the method provides for using the logarithmic values and the response curve to aim the light source.
