Self-imaging technique for beam collimation Sánchez Brea, Luis Miguel Torcal Milla, Francisco José Herrera Fernández, José María Morlanes, Tomás Bernabeu Martínez, Eusebio A simple collimation technique based on measuring the period of one self-image produced by a diffraction grating is proposed. Transversal displacement of the grating is not required, and then automatic single-frame processing can be performed. The self-image is acquired with a CMOS camera, and the period is computed using the variogram function. Analytical and experimental results are obtained, which show the simplicity and accuracy of the proposed technique. 2023-06-19T14:59:06Z 2023-06-19T14:59:06Z 2023-06-19T14:59:06Z 2014 journal article https://hdl.handle.net/20.500.14352/35040 0146-9592 10.1364/OL.39.005764 eng DPI2011-27851 open access Optical Society of America
