Abstract: The Crab pulsar and its pulsar wind nebula are predominantly sources of non-thermal radiation (through synchrotron, curvature, and inverse Compton processes), which is indicated not only by the broadband spectral continua but also by the strong polarisation that is measured. The outstanding brightness of the Crab across the electromagnetic spectrum makes it the ideal target to investigate polarisation at all wavelengths where suitable instrumentation is available. In this paper we compare the spatially resolved polarisation images from HST with the high-time resolution measurements from the OPTIMA polarimeter and conclude that the highly polarised inner knot next to the pulsar contributes substantially to the off-pulse polarisation.
