Single-Bit Hologram

Application ID: 34921

When two coherent light beams intersect, an interference pattern appears. If this occurs in a material that is sensitive to light, with intensities greater than a certain exposure threshold, the interference pattern is recorded in the material as a modulation of the refractive index and a hologram is produced.

In this tutorial model, a beam enters a holographic material from the left boundary while another enters it from the top boundary. This simulates a bit-by-bit holographic data storage, including data recording and retrieval. In the recording process, the two beams intersect and create an interference fringe pattern, which is recorded in the hologram carrying the single-bit data.

This model example illustrates applications of this type that would nominally be built using the following products:
