Web23 Sep 2024 · Talbot interferometry in conjunction with moiré phenomenon has been used for the measurement of focal length of a lens and radius of curvature of spherical … The optical Talbot effect can be used in imaging applications to overcome the diffraction limit (e.g. in structured illumination fluorescence microscopy). Moreover, its capacity to generate very fine patterns is also a powerful tool in Talbot lithography. In experimental fluid dynamics, the Talbot effect has been … See more The Talbot effect is a diffraction effect first observed in 1836 by Henry Fox Talbot. When a plane wave is incident upon a periodic diffraction grating, the image of the grating is repeated at regular distances away from the … See more Due to the quantum mechanical wave nature of particles, diffraction effects have also been observed with atoms—effects which are similar to those in the case of light. Chapman et al. carried out an experiment in which a collimated beam of sodium atoms … See more • Angle-sensitive pixel See more The nonlinear Talbot effect results from self-imaging of the generated periodic intensity pattern at the output surface of the periodically poled LiTaO3 crystal. Both integer and fractional nonlinear Talbot effects were investigated.
