We demonstrated the generation of a cylindrical vector laser beam using a pentaprism interferometer. The solid-state interferometer was made up of a trapezoid and right-angle prism, whose hypotenuse face was implemented with a polarization beam splitter coating that split a rotated TEM01 mode beam into two orthogonal polarizations. The Ppolarized beam was reflected inside the prism twice, allowing...
In this study a modified method of Talbot interferometry is developed to evaluate the curvature of an object. The tilt angle of moiré fringe formed by two gratings is related to the wavelength, the grating periods, the angle between these two gratings, and the object curvature. Therefore, substituting the known experimental parameters into a special derived equation the object curvature can be evaluated...
