Spatially resolved spectral interferometry for determination of subsurface structure.
We describe an instrument capable of obtaining two-dimensional images of subsurface structure in real time with no moving parts. The technique is based on spectral interferometry and uses an imaging spectrograph to obtain spatially resolved spectra. A test sample consisting of microscope coverslips and a Ronchi grating was measured, illustrating the system's depth resolution of 38 mum and trans...
متن کاملCorrigendum: Determining Chemically and Spatially Resolved Atomic Profile of Low Contrast Interface Structure with High Resolution
It was brought to the authors’ attention that the original paper contains the following errors. (i) We reported a 0.05% electron density contrast between silicon and boron carbide. There was a calculation error in computing this number and the correct contrast is 0.5%. This is one order of magnitude lower than what can be studied using hard x-ray reflectivity. Therefore, with this revised elect...

متن کاملDetermining Chemically and Spatially Resolved Atomic Profile of Low Contrast Interface Structure with High Resolution
We present precise measurements of atomic distributions of low electron density contrast at a buried interface using soft x-ray resonant scattering. This approach allows one to construct chemically and spatially highly resolved atomic distribution profile upto several tens of nanometer in a non-destructive and quantitative manner. We demonstrate that the method is sensitive enough to resolve co...
متن کاملMid-infrared interferometry with high spectral resolution
The Infrared Spatial Interferometer (ISI) is a three telescope interferometer system that operates near 11 microns wavelength using heterodyne detection with CO2 lasers as local oscillators. Stellar measurements have been made using consistent instrumentation for 20 years, allowing comparisons of stellar sizes of red giant and Mira stars over time intervals which are long in comparison to stell...
