Integrated optical means for micro holograms recording

Toward a compact, full-color holographic printer

“…In previous work, we used 'waveguide hologram' (WGH) technology to make a microhologram recording in a single color. 3 WGH uses total internal reflection on the optical media boundary for the fine separation of diffracted and non-diffracted beams. 4 We reduced the holographic printer's size, but only for single-color holograms.…”
