The authors present results of infrared speckle interferometry of several OH/IR stars at 5 and 10 μm. Two image reconstruction techniques have been developed for use even when the objects are only partially resolved. Most of the sources appear to be dominated by unresolved, <0arcsec.1 cores surrounded by partially resolved circumstellar shells. The sources appear to be symmetric within experimental errors.
