Abstract
A system for aircraft landing light alignment which includes a target of photocells distributed in a cross-like manner with a single photo detector centered about the common point of the cross-like distribution. A signal processing circuit coupled to the output of the target includes electronic readout devices distributed in a cross-like manner for indicating which way the beams should be directed to provide correct light adjustment. The aircraft landing light alignment system includes signal processing of photo detector derived signals which measures only the outer fringes of the Gaussian beam distribution.
