      abstract     = {In single pixel imaging (SPI) an image is sampled with an
                      orthogonal basis projected by a programmable optical element
                      like a digital micromirror array or a spatial light
                      modulator. The reflected or diffracted light is collected by
                      a lens and measured with a photodiode or bucket detector. In
                      this work we demonstrate that SPI of laser light fields can
                      exhibit cross talk with its phase when the bucket detector
                      is not sufficiently large (i.e. fast photodiodes) and does
                      not integrate the full spectrum of each basis element. In
                      that regime, structured phases can emerge from errors in the
                      optical or light collection system (i.e. misaligned optical
                      elements or aberrations) and can appear in the reconstructed
                      amplitude image. We show this behavior in simulations and
                      experiments where the reconstructed amplitude image will
                      exhibit phase cross-talk if the detector size is smaller
                      than between $50\%$ and $75\%$ of the maximum area spanned
                      by the projected spectrum of the measurement basis. This is
                      important because photodiodes with a fast response time have
                      a small effective area.},
