In many machines the beam is tilted in the transverse plane, but the SRI technique only allows to directly measure the size of the projection of the beam shape along the axis connecting the two apertures. A method to fully reconstruct the beam in the transverse plane using SRI has been developed and successfully tested at the ALBA synchrotron light source. This report shows the full beam reconstruction technique and presents the results at ALBA. Moreover, we also discuss how this technique could improve the measurement of very small beam sizes, improving the resolution of standard SRI.
