Complementary Multi-Band Wide-Angle Chromatography Filters in 3D Display System
A wide-angle complementary treble-bandpass filter is prepared based on the imaging principle of wavelength-division 3D technology. Via the investigation of film materials, suitable materials are selected as the equivalent spacer layer of the Fabry-Perot filter, which improves energy dispersion and enhance the bandpass transmissivity at a large incident angle of light. With the adjustment of the amount of the reactive gas of inductive coupled plasma, the extinction coefficient of Nb2O5 material can be reduced and the film transmissivity at a short wavelength can be enhanced. The experimental test and analysis results show that the prepared complementary treble-bandpass filters process the transmissivity of larger than 92% at each bandpass when light incident at 0°--30°. Moreover, the transmitted light satisfies the color balance index and meets the design requirements.
