The non-periodic pinhole array filtering of a spatial light modulator (SLM) is proposed for filtering the high-order noise and DC noise of a holographic display. Conventionally, DC and high-order noise sources are filtered by a 4f filtering system. Because the 4f filtering system requires a long optical path length, noise filtering is a stumbling block when attempting to realize a compact holographic display. By contrast, the proposed method simply uses a thin filter fabricated by photolithography. In order to verify this concept, we confirmed the feasibility of the filter with a numerical simulation and with a custom-made non-periodic pinhole array filter used in a practical experiment. The proposed method was shown to have the potential to be used in applications ranging from compact wearable devices to table-top holographic displays.

We have observed multiple-order diffraction from photorefractive gratings formed by two input beams of comparable intensity that interfere in a single crystal of SBN:Ce. High-order diffraction occurs both in the direction of two-beam coupling gain and in the opposite direction. These results are in good agreement with the predictions of a theoretical model that interprets high-order diffraction as a form of Raman-Nath scattering from a highly anharmonic diffraction grating that is formed by a light intensity distribution having a large depth of modulation.
