The present invention relates to a strap down SAL seeker that includes an optical system having an engineered diffuser for transforming a laser spot into a uniform distribution of optical energy with a predetermined shape. The predetermined shape is preferably a square "top hat" or uniform scatter pattern. The SAL seeker further includes a silicon quad detector, having a focal plane defined by at least two axes. The detector is operatively associated with the engineered diffuser, and it generates signals indicative of the position of the optical energy ...
I claim: 1. A semi-active laser (SAL) seeker, comprising: an optical system having a diffuser that homogenizes input illumination of incident laser radiation, spreads said incident radiation within a predetermined divergence angle and according to a predetermined shape, and establishes a predetermined intensity profile for said incident radiation; and a detector, having a focal plane defined by at least two axes, operatively associated with the diffuser, such that when the homogenized and spread incident radiation is projected onto said detector, the de...
