Ghost images for optical systems with tilted object plane

Ghost images are formed by light that is partially reflected by optical surfaces. Ghost images may cause contrast reduction and may veil parts of the nominal image. Performing ghost image analysis during the design stage is important to ensure the success of the system. In a previous paper (Applied Optics,...

Measuring the refractive index of double-clad fibers using an interferometric...

Multiple-beam Fizeau interferometry is an accurate, simple, and nondestructive technique in the field of fiber research. Inserting the fiber into the liquid silvered wedge causes the fringes to shift across the fiber region with respect to the fringes at the liquid region. Fringe shift is a function...

Optische Systeme ohne Rotationssymmetrie : Bestimmung von Bildlage und Bildori ...

Bei der Abbildung mit rotationssymmetrischen optischen Systemen lässt sich die Lage der Gauß‘schen Bildebene direkt über paraxiale Beziehungen ermitteln. Werden jedoch optische Systeme ohne Rotationssymmetrie betrachtet, muss ein anderer Ansatz gewählt werden. In diesem Beitrag diskutieren wir unterschiedliche...
