• openAccess   Centroid propagation through optical systems with ABCD kernels and nonuniform or finite apertures 

      Lancis, Jesús; Martinez Cuenca, Raul; Ares, Jorge; Bará, Salvador Optical Society of America (2010-07)
      If the propagation of a light field can be satisfactorily described by a diffraction integral with an ABCD kernel, the propagation of its irradiance centroid is completely determined by the corresponding ABCD ray-transfer ...
    • openAccess   Closed-loop adaptive optics with a single element for wavefront sensing and correction 

      Martinez Cuenca, Raul; Durán, Vicente; Arines, Justo; Ares, Jorge; Jaroszewicz, Z.; Bará, Salvador; Martínez-León, Lluís; Lancis, Jesús Optical Society of America (2011)
      We propose a closed-loop adaptive optical arrangement based on a single spatial light modulator that simultaneously works as a correction unit and as the key element of a wavefront sensor. This is possible by using a liquid ...
