  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. The delay-line current-biased
kinetic-inductance detector (CB-KID) is a two-dimensional superconducting
sensor with a high temporal resolution and multi-hit capability. We demonstrate
that the 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 in the transmission spectrum induced
by Bragg diffraction and nuclear resonance absorption in YbSn$_3$ single
crystals. We successfully drew the orientation mapping of YbSn$_3$ crystals
based on the analysis of observed Bragg-dip positions in the transmission
spectrum.
