SUMMARY We have developed the high speed bandpass liquid crystal filter with narrow full width at half maximum (FWHM) of 5 nm for real-time multi spectral imaging systems. We have successfully achieved short wavelength-switching time of 30 ms by the optimization of phase retardation of thin liquid crystal cells.
