The reverse illumination optical method, by means of which solar concentrator overall alignment and aligning elements are checked, areas of extreme distortion are identified, and receiver intercept factors are determined, involves viewing the concentrator on its optical axis and through a telescope located several kilometers away. The method is simpler and less expensive than ray tracing, but does not detail the magnitude and direction of slope errors. Portions of the concentrator aperture not filled by the image of a high visibility target are ineffective in concentrating the sun's energy on a receiver of the same dimensions as the target. Image analysis of these records yields a quantitative measure of reflector alignment and intercept factor for the collector.
