For the effective interferometric imaging at pulsed neutron sources, we have developed the Talbot-Lau interferometer which works at several wavelengths, and demonstrated its operation by observing the visibilities of moirE fringes in different wavelength conditions. An absorption grating as an analyzer was fabricated by imprinting of metallic glass for the first time, and showed a well-controlled shape. Using such a grating, we have succeeded in interferometric imaging for the samples of metal rods at a wavelength of 5 angstrom.
