Gómez Pedrero, José Antonio ; Rodríguez Ibáñez, Diego ; Alonso Fernández, José ; Quiroga Mellado, Juan Antonio | SPIE-International Society of Optical Engineering | 2015With the advent of techniques devised for the mass production of optical components made with surfaces of arbitrary form (also known as free form surfaces) in the last years, a parallel development of measuring systems adapted for these new kind[...]texto impreso
Rodríguez Ibáñez, Diego ; Gómez Pedrero, José Antonio ; Alonso Fernández, José ; Quiroga Mellado, Juan Antonio | The Optical Society Of America | 2016-03-21A new method for fitting a series of Zernike polynomials to point clouds defined over connected domains of arbitrary shape defined within the unit circle is presented in this work. The method is based on the application of machine learning fitti[...]texto impreso
Quiroga Mellado, Juan Antonio ; Rodríguez Ibáñez, Diego ; Alonso Fernández, José | Springer London Ltd. | 2013-09This paper proposes a calibration procedure for the squareness error of small-sized coordinate measuring machines like those used for ophthalmic lenses quality control. The proposed procedure only requires a spherical lens as a reference surface[...]
