Abstract: Abstract. Aspherical, free-form, and off-axis asymmetric optical elements often exhibit high dynamic range wavefront errors (HDR-wavefronts) during measurement. Wavefront sensing technology can currently be broadly categorized into two main types: interferometric and non-interferometric. Interferometric methods,… read more here.
