- Manufacturing Of A Fiber Optic Young's Double Pinhole Interferometer For Use As A 3D ProfilometerPennington, Timothy L.; Wang, Anbo; Xaio, Hai; May, Russell G. (Optical Society of America, 2000-05-01)The method used to manufature a Young's double pinhole interferometer is discussed. This interferometer is destined to be used in a surface profilometer using two wavelengths so that the zero order fringe can be determined. Hence stringent requirements are placed on the absolute length difference between the two output fibers of a single mode coupler. These requirements are discussed along with the manufacturing process. The interferometer is shown along with measurements showing a length difference on the order of 6 mu m.
