“…Although the single-shot intensity measurements are used indeed in these configurations, other additional information are also necessary or extra optical devices are required to generate additional phase-shifting holograms. The configurations in Nobukawa et.al [36] and Zhang et.al [51] are such two typical examples. In [51, Fig.…”

“…Such configurations are ideally suited for static objects but not for dynamic ones especially not for the vivo having very short life span (c.f. [51]). Correspondingly, a single-shot (requiring only one fixed θ in (1.1)) intensity based reconstruction approach is required for the dynamic imaging.…”

The phase-shifting digital holography (PSDH) is a widely used approach for recovering target signals by their interference (with reference signals) intensity measurements. Such reference signals are traditionally from multiple shots (or multiple phase-shiftings) of the reference wave. However, the imaging of dynamic target signals requires a single-shot PSDH approach, namely, such an approach depends only on the intensity measurements from the interference with the single reference signal (being from the single phase-shifting of the reference wave). In this paper, based on the uniform admissibility of plane (or spherical) reference wave and the interference intensity-based approximation to quasi-interference intensity, the nonnegative refinable function is applied to establish the single-shot PSDH in Sobolev space. Our approach is conducted by the intensity measurements from the interference of the target signal with a single reference signal. The main results imply that the approximation version from such a single-shot approach converges exponentially to the signal as the level increases. Moreover, like the transport of intensity equation (TIE), our results can be interpreted from the perspective of intensity difference.

“…Unfortunately, the need for multiple recording of holograms disqualifies the phase-shifting technique from being a candidate for 3D imaging of the dynamic scene [9]. Even though a single-shot phase-shifting DH has been carried out by Zhang et al [10], the technique is complicated because of its requirement of additional optical components and multiple CCDs that have to be aligned precisely. Off-axis holography ensures spatial separation of the extraneous terms so that these terms can be numerically removed.…”

We propose a method for carrying out three-dimensional (3D) display based on single-shot digital holography. The 3D display is realized from a digital hologram (DH) by displaying the complex function recovered through the constrained optimization approach on a phase-only spatial light modulator (SLM). A DH of a multiplane object is recorded in a near on-axis configuration, and the complex function corresponding to the object in the hologram plane is recovered. The recovered function is converted into a phase-only function, and it is displayed on a phase SLM. The optical reconstruction through simple diffraction from the SLM reproduced the 3D scene, and the image reconstructed at each plane has been observed.

“…In the PSM, the image sensor resolutions can be used to the maximum, but the target object type is limited to stationary targets because recording of multiple holograms with phase-shifting is required. Singleshot PSMs using multiple image sensors [14][15][16], phaseshifting arrays [17] or polarization imaging cameras [18][19][20][21][22][23][24][25][26][27] have been proposed, but the optical systems required are complex and the increased costs also cannot be ignored. In contrast, the FTM enables high-speed measurements because the object wave can be extracted from a single hologram when using this method.…”

The Fourier transform method (FTM), which can reconstruct a wavefront from a single hologram, is widely used in digital holography (DH) as a reconstruction technique. However, the space-bandwidth product (SBP) is limited because of the frequency filtering required. We propose a wavefront reconstruction algorithm based on compressed sensing that can obtain a high SBP for use instead of the FTM. The proposed method can reconstruct a high-SBP wavefront by solving the hologram recording model with total variation regularization. We demonstrate the proposed method’s effectiveness via simulations and experiments. The method can be applied to conventional off-axis DH without alteration and thus can be applied in various fields.
