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.

Method and apparatus are disclosed for determining the straightness of a lumber cut. A transit type of precision telescope is positioned to view in a vertical sweep plane essentially parallel to that of the cut surface of the timber stock on the log carriage. A hand held scale is placed against the cut surface with a constant, spring controlled force in a plurality of positions distributed over the cut surface. The scale is read by the telescope in each position and the readings compared to determine the degree of straightness of the saw cut.
