Automatic procedure for aberration compensation in digital holographic microscopy and applications to specimen shape compensation.
We present a procedure that compensates for phase aberrations in digital holographic microscopy by computing a polynomial phase mask directly from the hologram. The phase-mask parameters are computedExpand
