We investigate cholesteric liquid crystal (CLC) orientation in a hollow fiber by microscopic observation and reflection spectrum measurement. The existence of helical structure in the fiber is confirmed by comparing the reflection spectra of CLC in the fiber with that of CLC in a sandwich cell. The results of reflection measurement and microscopic observation indicate that the CLC helix is oriented concentrically in the fiber. FDTD simulation
