Tomography & Holography
sample. Above, a 360 degree high-precision, air-bearing, rotation stage is used for tomography. Upon this basis, a high-resolution XYZ piezo stage for ultra-fine positioning over a stroke of up to 400 μm is [...] for spatially resolved diffraction, and as quasi point sources for holographic imaging. PI’s XYZ piezo stage holding a piezoelectric sample for investigations on collective lipid bilayer dynamics excited [...] ultra-high-precision XYZ-scans. With this, on-the-fly measurements of live cells are perfomed scanning an area of 100 μm × 100 μm. A special linearization software inside the digital piezo controller allows
