A two‐dimensional X‐ray scattering system developed around a CCD‐based area detector is presented, both in terms of hardware employed and software designed and developed. An essential feature is the integration of hardware and software, detection and sample environment control which enables time‐resolving in‐situ wide‐angle X‐ray scattering measurements of global structural and orientational parameters of polymeric systems subjected to a variety of controlled external fields. The development and operation of a number of rheometers purpose‐built for the application of such fields are described. Examples of the use of this system in monitoring degrees of shear‐induced orientation in liquid‐crystalline systems and crystallization of linear polymers subsequent to shear flow are presented.
