Abstract: An imaging device (10) includes an array (18) of picture elements (16) or pixels, each of which is responsive to incident radiant energy to provide an output signal. The array (18) consists of pixels (16) in adjacent horizontal rows, each row having a certain pitch (P) or center-to-center distance between pixels. Each alternate row is horizontally offset by a distance equal to one-half of a row pitch from each adjacent row to form a "brick wall" or quincunx pattern. An azimuthal traverse of the quincunx focal plane array (18) provides twice the azimuthal resolution and approximately 140 percent of the minimum resolvable temperature measurement capability of conventional focal plane arrays.
