Paper Abstract

When an LWIR sensor is calibrated, the question generally arises as to what the precision, accuracy, and repeatability are for the calibration. The measurement precision is readily determined; however, general agreement does not exist in the LWIR community as to the formulation and interpretation of the terms "accuracy" and "repeatability". A derivation is presented in this paper in which a logical formulation of these terms is obtained. Forms for both short-term and long-term uncertainties are given, In addition, the use of confidence intervals in connection with sensor calibration is discussed, along with an appropriate example. A compilation of uncertainity terms and the definitions of these terms are proposed for adoption by the LWIR community,
