Extended depth of field with absolute position detection in multi-wavelength digital holography

We present a novel approach for detecting the absolute position of surfaces in multi-wavelength holography. We extent the depth of field from ~0.08 mm to ~3 mm and get the absolute position with accuracies better than10 µm.
