    We report an Optical Differentiation Wavefront Sensor based on a telephoto lens system and binary pixelated filters. It provides a five-fold reduction in the system length compared to a 4fsystem with identical effective focal length. Measurements of phase plates with this system are compared to measurements performed with a commercial low-coherence interferometer. The telephoto-lens-based system can measure wavefronts with accuracy better thanĪ»/10 Root Mean Squared (RMS) atĪ»=633 nm. Experimental investigation shows that the system has a high tolerance to components alignment errors.

    Wavefront generated by freeform phase plate is measured with an optical differentiation wavefront sensor. Comparison of the measurement with a commercial scanning interferometer shows M0 (A=633 nm) agreement, demonstrating its potential for metrology applications.
