The calibration of photographic edges at NBS
Abstract
The method by which photographic edges are calibrated is presented and discussed in some detail. The programs associated with the computational aspects of the analysis are listed, covered in narrative form, and their limitations and options are presented. The possible use of these edges to determine microdesitometer transfer function is discussed and limitations and relative error of all the calculations and procedures are covered in detail. Program listings are in BASIC language.
