The calibration target element can include an outer perimeter, a modular transfer function (MTF) testing area, a through hole extending through the at least one calibration target, and a plurality of slots extending through the at least one calibration target. The MTF testing area can comprise a light-absorbing surface and at least one slant edge that is non-orthogonal with respect to any side of the outer perimeter. The black body source can be positioned behind the at least one calibration target elements and configured to emit black body radiation such that the black body radiation passes through the through hole and the plurality of slots.
