We proposed a tunable narrow-bandpass filter using a blue phase liquid crystal etalon filter and a multi-bandpass interference filter for real-time multi-spectral imaging systems. We theoretically clarified this filter has high transmittance > 80% and confirmed a control of transmission wavelengths can be achieved by this filter.
