ABSTRACT:
Methods for making optically blind reference pixels and systems employing the same. The reference pixels may be configured to be identical to, or substantially identical to, the active detector elements of a focal plane array assembly. The reference pixels may be configured to use the same relatively longer thermal isolation legs as the active detector pixels of the focal plane, thus eliminating joule heating differences. An optically blocking structure may be placed in close proximity directly over the reference pixels.
