“…Cavities can also sustain orthogonal modes for reference beams according to their eigenmodes. These eigenmodes are an inherently orthogonal set of functions, which means that they can be used as orthogonal phase codes to providing another DOF in HDSS multiplexing [8][9][10], bringing it closer to the 3D limit when effectively combined with angular multiplexing…”

Abstract:Resonant optical cavities have been demonstrated to improve energy efficiencies in Holographic Data Storage Systems (HDSS). The orthogonal reference beams supported as cavity eigenmodes can provide another multiplexing degree of freedom to push storage densities toward the limit of 3D optical data storage. While keeping the increased energy efficiency of a cavity enhanced reference arm, image bearing holograms are multiplexed by orthogonal phase code multiplexing via Hermite-Gaussian eigenmodes in a Fe:LiNbO 3 medium with a 532 nm laser at two Bragg angles. We experimentally confirmed write rates are enhanced by an average factor of 1.1, and page crosstalk is about 2.5%. This hybrid multiplexing opens up a pathway to increase storage density while minimizing modification of current angular multiplexing HDSS.

“…However, there are cases where an SLM also appears in the reference channel as an address selector, 9,10 or as a phaseshifting device in a setup of an in-line digital holographic recorder for the purpose of removing the twin image and the bias term from the recorded hologram. 11,12 Besides the usage for phase shifting, the SLM can be used as a beam splitter between the reference and the object beams and as a diffractive lens for controlling the location of the beam focuses.…”

Abstract. Today, spatial light modulators (SLMs) offer the world of digital holography a robust technology that can be incorporated into hologram recorders. This review surveys recent developments related to the role of SLMs in a family of incoherent digital hologram recorders termed Fresnel incoherent correlation holography (FINCH). Two systems branching out from FINCH, and discussed herein, are a confocal version of FINCH and a synthetic aperture FINCH-based system.

“…These include optical encryption-decryption [1][2][3], holographic optical memory or datastorage [4,5], and optical joint-transform correlation (JTC) [6]. Well-controlled modulation of phase in 2D space has become conveniently straightforward with the emergence of phaseonly spatial light modulators (PO-SLM).…”

An improved implementation of the reverse phase contrast (RPC) method for rapid optical transformation of amplitude patterns into spatially similar phase patterns using a high-speed digital micromirror-array device (DMD) is presented. Aside from its fast response, the DMD also provides an electronically adjustable and inherently aligned input iris that simplifies the optimization of the RPC system. In the RPC optimization, we illustrate good agreement between experimentally obtained and theoretically predicted optimal iris size. Finally, we demonstrate the conversion of a binary amplitude grating encoded on the DMD into a binary (0-π) phase grating.
