We present a holographic imaging device with a low-coherence light source that uses the reflection of the objective lens as reference illumination. This results in a simple setup and allows applications to microscopy with only small modifications of the setup for aberration measurements. In addition, it opens the prospects to in vivo ophthalmic imaging. We present in vitro experiments using a resolution test target to quantify the system performance. We demonstrate that we can achieve diffraction-limited resolution and show the possibility of aberration correction. We also present preliminary results using a scattering sample.
