Atmospheric coherence times in interferometry: definition and measurement
Current and future ground-based interferometers require knowledge of the atmospheric time constant t0, but this parameter has diverse definitions. Moreover, adequate techniques for monitoring t0 still have to be implemented. We derive a new formula for the structure function of the fringe phase (piston) in a long-baseline interferometer, and review available techniques for measuring the atmosph...
متن کاملCoherence scanning interferometry: linear theory of surface measurement.
The characterization of imaging methods as three-dimensional (3D) linear filtering operations provides a useful way to compare the 3D performance of optical surface topography measuring instruments, such as coherence scanning interferometry, confocal and structured light microscopy. In this way, the imaging system is defined in terms of the point spread function in the space domain or equivalen...
متن کاملNeedle-based refractive index measurement using low-coherence interferometry.
We present a novel needle-based device for the measurement of refractive index and scattering using low-coherence interferometry. Coupled to the sample arm of an optical coherence tomography system, the device detects the scattering response of, and optical path length through, a sample residing in a fixed-width channel. We report use of the device to make near-infrared measurements of tissues ...
متن کاملSurface profile measurement using spatially dispersed short coherence interferometry
Improved online techniques for surface profile measurement can be beneficial in high/ultra-precision manufacturing, in terms of enabling manufacture and reducing costs. This paper introduces a spatially dispersed short-coherence interferometer sourced by a super luminescent diode. This technique uses a broadband light source, which is spatially dispersed across a surface using a reflective grat...
متن کاملDispersion cancelled low coherence interferometry
Even-order dispersion cancellation, an effect previously identified with frequencyentangled photons, is demonstrated experimentally for the first time with a linear, classical interferometer. A combination of a broad bandwidth laser and a high resolution spectrometer was used to measure the intensity correlations between anti-correlated optical frequencies. Only 14% broadening of the correlatio...
