Shifting selectivity of collinear volume holographic storage

Diffraction Property of Collinear Holographic Storage System

“…11. The figures from left to right are followed with 2-D shifting selectivity, 2-D shifting selectivity after thresholding and its enlarged pattern, 1-D shifting selectivity [22].…”

“…The simulation result of the impulse response for a point located at the center of the signal plane corresponding to the reference patterns in Fig. 11 [22].…”

Study of collinear VHS: point spread function and shift selectivity

“…We can easily find that the shifting selectivity is a function of the Fourier transform of the intensity distribution of the reference pattern [14]. Besides, Eq.…”

“…(11) indicates that the shifting selectivity relates to the autocorrelation of the Fourier transform of the reference pattern [14]. Since the broader reference pattern will cause narrower Fourier transform pattern, Eq.…”

Orthogonal reference pattern multiplexing for collinear holographic data storage

“…Its optical setup is compact and tolerant to disturbances of the environment, such as mechanical vibration [5,6], temperature variation [7,8], and wavelength shift [9,10], which makes producing the practical holographic data storage systems easier than the conventional two-axis holography. In CHDS, the reference pattern (RP) and the signal pattern are uploaded simultaneously on the same spatial light modulator (SLM) [11,12]. The RPs can be switched at the same frame rate with the signal beam, making it possible to change the signal and reference beams synchronously during the recording and reconstruction process.…”
