Color-coded character-recognition experiment with wavelength-triplexed, reflection-type holographic filters

Not Accessible

Your library or personal account may give you access

Abstract

Color-coded, simultaneous recognition of several characters is experimentally performed using wavelength-triplexed, reflection-type holographic filters made with the primary wavelengths, 632.8, 514.5, and 488.0 nm. Helpful data on the diffraction efficiency and the spectrally diffracted intensity of reflection-type holograms are presented.
