    The Ronchi test is a widely used tool in the optical shop, because of its capability of measuring wide-field profiles of optical quality surfaces through its important ray slope dynamic range. Although many applications ...
  • Adaptive feedback control in self-mixing interferometry using active optical elements 

    Atashkhooei, Reza; Zabit, U; Royo Royo, Santiago; Azcona Guerrero, Francisco Javier; Sergievskaya, Irina (Universidad de Murcia, 2011)
    Conference report
    Open Access
    A voltage-controlled liquid lens has been used as an adaptive optical element integrated in a conventional self-mixing interferometry setup. The lens is used to control the optical feedback level and the focus position of ...
  • Fast correction in adaptive optical system using block control 

    Sergievskaya, Irina; Royo Royo, Santiago; Riu, Jordi; Ares Rodríguez, Miguel (Universidad de Murcia, 2011)
    Conference report
