Using Image Processing of A Fabry -Perot Interferometer to Determine the Defects of Leneses by Using He-Ne Laser
Main Article Content
Abstract
A design of a Fabry -Perot interferometer system was constructed
to determine the precise value of the wavelength which is required in spectml studies depending on varying medium pressure where the refractive index was a function of pressure at a constant distance between the two mirrors by using a Hc-Ne laser (632.8) tun as a coherent source .
The (fmee) (t) and the coefficient of finesses (F) and the visbility
of the fringes (V) has been calculated . Image processing \\•as used and its result can be relied on verifying the defects of the manuli1ctured lenses used in the optical instruments.
