Complex holograms in PTR glass recorded by using digital micromirror device (Conference Presentation)

Paper Abstract

An approach for recording complex holograms using two beam interference setup incorporating a light modulating device in one of the arms of the holographic setup is proposed. This allows the intensity profile of the beam reflected by the DMD to be adjusted to a pre-determined profile. Using an UV laser, the created interference pattern is recorded into PTR glass plate. The variable light amplitude exposure of the glass is converted to a refractive index change after thermal treatment step. The DMD device makes possible the incorporation of zones in the hologram where there is no interference pattern and therefore there is no hologram. Such custom designed holograms can find applications in laser resonators or as spatially sensitive wavelength filters. In addition, the holograms recorded in the volume of the PTR glass are practically insusceptible to surface damage, changes in the environment and other factors from which holograms recorded in polymers suffer.
