On the basis of this review three precise definitions of a direct view imagers eyepiece diopter are presented. One of these definitions is determined as optimal fit to describe the perception of human observers. Further on, design and measurement uncertainties of diopter meters are discussed and rules of accurate measurements are formulated. Finally, recommendations for the maximum acceptable errors of the diopter scale of eyepieces of classic types of direct view imagers are presented, as well.}, type={Article}, title={Measurement of eyepiece diopter of direct view imagers}, URL={http://journals.pan.pl/Content/118352/PDF/OPELRE_28_2020_K_Chrzanowski.pdf}, doi={10.24425/opelre.2020.135373}, keywords={diopter, eyepiece, night vision devices, optical sight}, }
