Abstract : The aim of the study was to assess the current state of the current state of the art of measuring and computing the MTF/OTF of lenses or optical systems. It is intended to furnish guidance for the possible revision of Standard MIL-STD-150A, should it appear desirable and feasible to make wider use of the MTF concept in writing specifications for or making physical evaluations of optical systems. Data were collected to make comparisons of results obtained by different laboratories (a) of theoretical MTF values as computed from a lens design; (b) of actual measured MTF on a particular lens; and (c) to compare actual measurements with design predictions on the same lens.
