| description | A system (10) for focusing an array (12) of detectors. The invention (10) includes a target (16) disposed in the line-of-sight of the array (12). In accordance with the invention, the target (16) has a plurality of elongate apertures therein. The target (16) is mounted about the line-of-sight of the array relative to an axis extending through the plane of the input aperture of the array and transverse to the line of sight. The array (12) is sampled to provide a plurality of output signals. The output signals have amplitude minima and maxima corresponding to the detection of the apertures by individual detectors in the array (12). The maxima of the output signals are used to focus the array (12). |
