摘要：

We demonstrate the fabrication of a waveguide hologram and describe how a plane-wave output beam can be generated for the illumination of a finger for fingerprint image capture. Also, when using a diverging beam in the substrate as a reference wave, one obtains a set of gratings written in the hologram. The reflected light from the finger is spatially filtered by this hologram, providing bandpassed information back through the waveguide when it is viewed through the plate.
