Background intensity removal in Fourier transform profilometry: A comparative study
(OSA - The Optical Society, 2016)
We study the removal of the background intensity of fringe patterns via Empirical Mode Decomposition and the Hilbert Transform. Simulation results show that the latter provides a suitable background compensation with minimal ...
Experimental investigation of high-speed melt spinning by means of digital image analysis
(OSA - The Optical Society, 2016)
We carry out an experimental characterization via high-speed camera of Chill-Block Melt Spinning process by means of digital optical flow for melt ejection velocity calculation and temperature measurement. © OSA 2016.
Diffuser in Fractional Fourier Optics
(OSA - The Optical Society, 2016)
We propose a method for calculating a bandlimited diffuser with smooth spectrum in the Fresnel domain without any 2p phase ambiguities using the fractional Fourier transform. Such diffusers are necessary to avoid problems ...
