Lateral shearing interferometry of high-harmonic wavefronts.
We present a technique for frequency-resolved wavefront characterization of high harmonics based on lateral shearing interferometry. Tilted replicas of the driving laser pulse are produced by a Mach-Zehnder interferometer, producing separate focii in the target. The interference of the resulting harmonics on a flat-field extreme ultraviolet spectrometer yields the spatial phase derivative. A co...
متن کاملApplication of lateral shearing interferometry to 'stochastic inputs*
Lateral shearing interferometry is a simple and accurate method of measuring the shape of an optical wave front. However, the complex mathematics required in reduction of the interferograms has limited the adoption of this interferometric technique. A data reduction technique using Fourier analysis methods has been developed which makes lateral shearing interferogram reduction more flexible. Th...
متن کاملThermal Infrared Optical Metrology using Quadri-Wave Lateral Shearing Interferometry
We present the application of Quadri-Wave Lateral Shearing Interferometry (QWLSI), a wave front sensing technique, to characterize thermal infrared lenses for wavelengths within 8 and 14μm. Wave front sensing is not only a tool to quantify optical quality, but also to map the local (dust, scratches) or global possible defects. This method offers the crucial advantage that it yields an analyzed ...
متن کاملTransmission wavefront shearing interferometry for photoelastic materials.
A general analysis and experimental validation of transmission wavefront shearing interferometry for photoelastic materials are presented. These interferometers applied to optically isotropic materials produce a single interference pattern related to one phase term, but when applied to photoelastic materials, they produce the sum of two different interference patterns with phase terms that are ...
متن کاملDeterminants of Zeroth Order Operators
For compact Riemannian manifolds all of whose geodesics are closed (aka Zoll manifolds) one can define the determinant of a zeroth order pseudodifferential operator by mimicking Szego’s definition of this determinant for the operator: multiplication by a bounded function, on the Hilbert space of square-integrable functions on the circle. In this paper we prove that the non-local contribution to...
