Abstract

An imaging device including a focal plane array and capable of providing non-uniformity correction (NUC) without using a shutter outside the focal plane array. In one example, the imaging device includes a focal plane array that comprises an array of pixels arranged in rows and columns, the array of pixels corresponding to an imaging area of the focal plane array, the plurality of pixels including a first plurality of imaging pixels and a second plurality of reference pixels. The first plurality of imaging pixels are configured to receive incident electromagnetic radiation from a viewed scene and provide image signals, and the second plurality of reference pixels are shielded from receiving the incident electromagnetic radiation and are configured to produce non-uniformity correction signals.
