Heidrich","doi":"10.1364/dh.2021.dw4b.4","DOIUrl":"https://doi.org/10.1364/dh.2021.dw4b.4","url":null,"abstract":"We present a joint optimization framework for four-dimensional (4D) optical imaging: volumes and movements are reconstructed jointly in a higher space-time dimension, enabling faster convergence and better reconstruction quality of both the volumes and movements within a few minutes on modern GPUs. We verified the framework on digital holographic particle tracking velocimetry, a typical 4D optical imaging example. Experimental results are presented to show the efficiency of the proposed technique. © 2021 The Author(s) 1. Theory The temporal evolution of a volume o defines an apparent movement of the volume, known as fluid velocities. Motion flows can be numerically reconstructed from consecutive, rapid measurements of changing particle volumes. Under the assumption of incompressibility, i.e., divergence-free flow, the motion flow vt ∈ R3 relates temporally neighboring particle volumes from time t to t +1 [1]. That is, with x = (r,z): ot(x+vt)≈ ot+1(x), (1) where subscripts (t and t + 1) denote for two neighboring time frames. Given a sequence of indexed 2D images bt(r) of t = 1,2, · · · ,T , at each frame t, we would like to recover simultaneously its volume ot(x) and the associated 3D flow vector vt(x). By taking into consideration of the temporal coherence between neighboring frames, we jointly estimate volumes and fluid flows and this strategy optimizes for neighboring frames together, and hence closing the numerical reconstruction loop. These yield the following optimization problem: min o,v T ∑ t=1 ‖Aot −bt‖2 + τ T−1 ∑ t=1 ‖ot+1(x)−ot(x+vt)‖2 +priors(o)+priors(v), (2) where priors(v) may represent the smoothness and incompressible property [1,2] of the flow, and priors(o) represents the property of the volumes, usually is sparsity. Specifically, Eq. (2) is solved by alternating between solving particle volume o and solving volumetric movement flow v, as in Algorithm 1: min o T ∑ t=1 ‖Aot −bt‖2 + τ T−1 ∑ t=1 ‖ot+1(x)−ot(x+vt)‖2 +priors(o), min v τ T−1 ∑ t=1 ‖ot+1(x)−ot(x+vt)‖2 +priors(v).

At final iteration K In Eq. (2) and Eq. (3), A can be an optical system of holography or light field microscopy, where bt(r) are holograms or light field images. We take the holographic particle tracking velocimetry (HPTV) as an example. Specifically, we solve particles using FASTA iterative shrinkage algorithm [3], and solve flow using standard HornSchunck optical flow [4]. In the following, we evaluate our proposed approach on HPTV based on experimental hologram data. 2.
