Color visualization of phase object using Talbot interferometer

Journal of Optics, 1986
A method of color visualization of a phase object based on the Talbot effect is presented. If a grating is illuminated with a collimated white-light, the distance of the Talbot image will differ for different color. By placing an identical grating at a certain distance of negative or positive Talbot image, a single color output is extracted.

An electron Talbot-Lau interferometer and magnetic field sensing

Applied Physics Letters, 2013
We present a demonstration of a three grating Talbot-Lau interferometer for electrons. As a proof of principle, the interferometer is used to measure magnetic fields. The device is similar to the classical Moiré deflectometer. The possibility to extend this work to build a scaled-up electron deflectometer or interferometer for sensitive magnetic field ...

On Talbot's Bands and the Theory of the Lummer-Gehrcke Interferometer

Physical Review, 1921
New Simple Method of Observing Talbot's Bands.-If a thin strip of cover glass is immersed in a dispersive medium, such as a suitable mixture of CS 2 and benzene, with a refractive index such that the group velocity in it is less than in the plate, and if a vertical slit illuminated with white light is observed through the glass strip held in a ...

An elliptical Talbot interferometer for fiber Bragg grating fabrication

Review of Scientific Instruments, 2005
A simple and easily aligned two-mirror interferometer for fabricating Bragg gratings in optical bulk materials, waveguides, and fibers is presented. The interferometer consists of a simple phase mask splitting element and two dielectric mirrors optimized for maximum reflectance at an incident angle of 45 deg.

Phase tomography using an x-ray Talbot interferometer

SPIE Proceedings, 2004
X-ray phase tomography with X-ray Talbot interferometry (XTI) is reported. XTI employs two transmission gratings and generates a contrast corresponding to the differential phase shift caused by a sample. Quantitative phase measurement and tomographic image reconstruction with XTI are demonstrated for biological samples.
