Recent progress in high-power pulsed neutron sources has stimulated the development of the Bragg dip and Bragg edge analysis methods using a two-dimensional neutron detector with high temporal resolution to resolve the neutron energy by the time-of-flight method. A delay-line current-biased kinetic inductance detector (CB-KID) is a two-dimensional superconducting sensor with a high temporal resolution and multi-hit capability. Here, it is demonstrated that a delay-line CB-KID with a $$^{10}$$B neutron conversion layer can be applied to high-spatial-resolution neutron transmission imaging and spectroscopy up to 100 eV. Dip structures are observed in the transmission spectra of YbSn$$_{3}$$ single crystals, induced by Bragg diffraction and nuclear resonance absorption. The orientation mapping of YbSn$$_{3}$$ crystals is successfully drawn based on the analysis of observed Bragg dip positions in the transmission spectra.
