Quantitative analysis in the small‐angle light scattering technique for crystalline polymer studies is facilitated by the incorporation of charge‐coupled detectors and image digitization and processing schemes which enable the intensity and angular dependence of scattered light to be measured. This task, however, can only be successfully achieved if a calibration procedure, where each pixel in the camera is related to its respective scattering angle component, is first implemented. In this article, a rapid and convenient calibration procedure that uses the diffraction pattern from a grating with a predetermined center‐to‐center distance is outlined. © 1996 John Wiley & Sons, Inc.
