Abstract

We demonstrate the feasibility of bidirectional image transmission through a physically thick scattering medium within its memory effect range by digital optical phase conjugation. We show the bidirectional transmission is not simply the consequence of optical reciprocity. We observe that when the spatial light modulator (the device performing the digital optical phase conjugation) is relayed to the middle plane of the medium, the memory effect will be fully exploited and thus the transmitted images will have maximum field of view (FOV). Furthermore, we show that the FOV can be expanded n times by performing n times wavefront measurements.

Figures (6)

Fig. 1
Fig. 1 Schematic of our approach for bidirectional image transmission through a thick scattering medium (showed as the gray turbid cube). (a) We first measure the diffused wavefront (green squiggly line) originating from a point source behind the medium using interferometry (the interferometer is not shown here for simplicity, see Fig. 2 for detailed setup), and then superpose the conjugated phase map of the measured wavefront on the SLM to compensate the diffused wavefront into a plane wavefront, which is then focused onto the CCD by a lens (L2). (b) An unknown object (far left) hidden behind the medium can be imaged onto the CCD (far right) after phase compensation. (c) A know object (far right) can also be projected (far left) through the medium from the other direction by phase pre-modulation. It should be noted that the SLM is plotted here as a transmissive element for simplicity, but in our experiments, we used a reflective SLM (Fig. 2).
Fig. 2
Fig. 2 The experimental setup for bidirectional image transmission through thick scattering media. BS: beam splitter, L: lens, LCVR: liquid crystal variable retarder, BE: beam expander, SF: single-mode fiber, BPF: bandpass filter, CCD: charge coupled device, SLM: spatial light modulator, DOPC: digital optical phase conjugation. The green and red arrows indicate the light path in the wavefront measurement step and the imaging step, respectively. To perform the projecting experiment, CCD2 and the elements in the red rectangular box are exchanged, and the light path will be inverse to that in the imaging step.
Fig. 3
Fig. 3 Images and projections captured by CCD2 after a 1 mm thick chicken breast slice. (a) The truth of a ‘butterfly’ object captured without any scattering medium. (b) Image of the ‘butterfly’ object without phase compensation after the thick chicken breast slice. (c) A 50x50 pixels region of the compensative phase map. (d-e) Image (d) and projection (e) of the ‘butterfly’ object when SLM displayed the compensative phase map and was relayed to the right surface of the slice. The FOV (full width at 1/5 maximum) for (d-e) are 0.6 mm x 0.6 mm and 0.5 mm x 0.5 mm, respectively. (f-g) Image (f) and projection (g) of the ‘butterfly’ object when SLM displayed the conjugated phase map and was relayed to the middle plane of the slice. The FOV (full width at 1/5 maximum) for (f-g) are 0.9 mm x 0.9 mm and 0.75 mm x 0.75 mm, respectively. (h-i) Image (h) and projection (i) of an object of Chinese letter ‘zhong’ when SLM displayed the conjugated phase map and was relayed to the middle plane of the slice. The size of the object is 0.5 mm x 0.5 mm.
Fig. 4
Fig. 4 Experimentally measured FOV for chicken breast slices. (a, b) FOV curves measured at different z r (the relative position between the SLM’s relay plane and the right surface of the scattering samples), for imaging (a) and projecting (b), respectively. Slice thickness is 1 mm. (c, d) Change of FOV width with z r , for 1 mm (c) and 2 mm (d) thick slices, respectively. ‘1/5′ and ‘1/2’ in the legends indicate full width at 1/5 and 1/2 maximum, respectively. The cyan dotted lines indicate the optimal z r where the FOV reaches its maximum.
Fig. 5
Fig. 5 Enlargement of the FOV by multiple times wavefront measurements. (a) Positions of the point source (red points) in each wavefront measurements. The ‘butterfly’ object is also shown to indicate the relative position between the object and the point source. (b-g) Images of the object captured by CCD2 when the SLM displayed the five conjugated phase maps and the synthesized map, respectively. (h-m) Projections of the object captured by CCD2 when the SLM displayed the same phase maps as in (b-g). Scale bar: 0.5 mm.
Fig. 6
Fig. 6 Relationship between FOV and z r (the relative position between the SLM’s relay plane and the right surface of the scattering samples), measured with silicon microsphere samples with different anisotropy factor g and thickness L. (a) g = 0.98, L = 0.5 mm. (b) g = 0.98, L = 1 mm. (c) g = 0.95, L = 0.5 mm. (d) g = 0.95, L = 0.8 mm. MFP = 0.1 mm for all samples. ‘1/5′ and ‘1/2’ in the legends indicate full width at 1/5 and 1/2 maximum. The cyan dotted lines indicate the optimal z r where the FOV reaches its maximum.
