Simultaneous acquiring and synthesizing images through an optical fiber on a moving mechanism
Authors: Lee Fu-Shin , Lin Chen-I , Guo Bo , Chiang Antony , Ho Pin-Hsien
Published: August 2021

The research prototypes an optical fiber-scanning mechanism for capturing fiber-acquired multiple images. First, the study develops an image processing firmware embedded in high-speed hardware for image cropping, rotation, sharpening, and stitching, especially synchronizing with the moving mechanism. Then, the embedded firmware successively builds panoramic images while iteratively acquiring images as the mechanism in motion. This research applies a 3D printing technology to prototype the mechanism components and employs servomotors for mechanism motions during the prototyping stage. Next, the mechanism guides the scanning motions to follow prescribed trajectories while capturing images of specified regions. Finally, the research embeds the firmware developed on a Linux OS platform into a high-speed controller board. The resolution tests verify that the best image resolution for the prototyped optical mechanism reaches 14.30 line pairs per millimeter, and the achievable image resolution for an inspected object is 35 μm. Through acquiring and synthesizing images simultaneously by the embedded firmware while the optical fiber-scanning mechanism is in motion, this research demonstrates that the developed system effectively constructs panoramic images for an endoscope device at a lower cost.
Use of dynamic reconstruction for parametric Patlak imaging in dynamic whole body PET
Authors: Chalampalakis Zacharias , Stute Simon , Filipović Marina , Sureau Florent , Comtat Claude
Published: August 2021

Dynamic whole body (DWB) PET acquisition protocols enable the use of whole body parametric imaging for clinical applications. In FDG imaging, accurate parametric images of Patlak K

i
can be complementary to regular standardised uptake value images and improve on current applications or enable new ones. In this study we consider DWB protocols implemented on clinical scanners with a limited axial field of view with the use of multiple whole body sweeps. These protocols result in temporal gaps in the dynamic data which produce noisier and potentially more biased parametric images, compared to single bed (SB) dynamic protocols. Dynamic reconstruction using the Patlak model has been previously proposed to overcome these limits and shown improved DWB parametric images of K

i
. In this work, we propose and make use of a spectral analysis based model for dynamic reconstruction and parametric imaging of Patlak K

i
. Both dynamic reconstruction methods were evaluated for DWB FDG protocols and compared against 3D reconstruction based parametric imaging from SB dynamic protocols. This work was conducted on simulated data and results were tested against real FDG dynamic data. We showed that dynamic reconstruction can achieve levels of parametric image noise and bias comparable to 3D reconstruction in SB dynamic studies, with the spectral model offering additional flexibility and further reduction of image noise. Comparisons were also made between step and shoot and continuous bed motion (CBM) protocols, which showed that CBM can achieve lower parametric image noise due to reduced acquisition temporal gaps. Finally, our results showed that dynamic reconstruction improved VOI parametric mean estimates but did not result to fully converged values before resulting in undesirable levels of noise. Additional regularisation methods need to be considered for DWB protocols to ensure both accurate quantification and acceptable noise levels for clinical applications.
Universal coupled theory for metamaterial bound states in the continuum
Authors: Huang Wei , Liu Songyi , Cheng Yu , Han Jiaguang , Yin Shan , Zhang Wentao
Published: August 2021

In this paper, we present a novel universal coupled theory for metamaterial bound states in the continuum (BIC) or quasi-bound states in the continuum (quasi-BIC) which provides ultra-high Q resonance for metamaterial devices. Our theory analytically calculates the coupling of two bright modes with phase information. Our method has much more accuracy for ultra-strong coupling comparing with the previous theories (the coupling of one bright mode and one dark mode and the two bright-mode coupling). Therefore, our theory is much more suitable for BIC or quasi-BIC and we can accurately predict the transmission spectrum of metamaterial BIC or quasi-BIC for the first time.

Authors: He Lu , Zhang Huizhen , Zhang Weixuan , Wang Yujing , Zhang Xiangdong
Published: August 2021

The polarization beam splitter (PBS) is the essential optical component, which is widely used in various optical instruments. Its robustness against perturbation is very necessary to all-optical classical and quantum networks. Here, we report the design of topologically protected vector edge states (dual-polarization with transverse electric and transverse magnetic modes) and PBS based on all-dielectric topological valley photonic crystal slabs. The topologically protected vector edge states have been realized for the first time using germanium photonic crystal slab with silica substrate. Based on such edge states, the topologically protected PBS has been designed and its robust property has been demonstrated by exact numerical simulations. Our proposed PBS is expected to be widespread applications for photonic integrated circuits and quantum information processing.

Authors: Tang Yuxia , Wang Shuxia , Huang Yingzhou , Fang Yurui
Published: August 2021

Benefiting from the induced image charge on film surface, the nanoparticle aggregating on metal exhibits interesting optical properties. In this work, a linear metal nanoparticle trimer on metal film system has been investigated to explore the novel optical phenomenon. Both the electric field and surface charge distributions demonstrate the light is focused on film greatly by the nanoparticles at two sides, which could be strongly modulated by the wavelength of incident light. And the influence of nanoparticle in middle on this light focusing ability has also been studied here, which is explained by the plasmon hybridization theory. Our finding about light focusing in nanoparticle aggregating on metal film not only enlarges the novel phenomenon of surface plasmon but also has great application prospect in the field of surface-enhanced spectra, surface catalysis, solar cells, water splitting, etc.
Cascade discrete memristive maps for enhancing chaos*
Authors: Yuan Fang , Bai Cheng-Jun , Li Yu-Xia
Published: August 2021

Continuous-time memristor (CM) has been widely used to generate chaotic oscillations. However, discrete memristor (DM) has not been received adequate attention. Motivated by the cascade structure in electronic circuits, this paper introduces a method to cascade discrete memristive maps for generating chaos and hyperchaos. For a discrete-memristor seed map, it can be self-cascaded many times to get more parameters and complex structures, but with larger chaotic areas and Lyapunov exponents. Comparisons of dynamic characteristics between the seed map and cascading maps are explored. Meanwhile, numerical simulation results are verified by the hardware implementation.

Impedance scaling for gold and platinum microelectrodes
Authors: Fan Bo , Wolfrum Bernhard , Robinson Jacob T
Published: August 2021

Objective. Electrical measurement of the activity of individual neurons is a primary goal for many invasive neural electrodes. Making these ‘single unit’ measurements requires that we fabricate electrodes small enough so that only a few neurons contribute to the signal, but not so small that the impedance of the electrode creates overwhelming noise or signal attenuation. Thus, neuroelectrode design often must strike a balance between electrode size and electrode impedance, where the impedance is often assumed to scale linearly with electrode area. Approach and main results. Here we study how impedance scales with neural electrode area and find that the 1 kHz impedance of Pt electrodes (but not Au electrodes) transitions from scaling with area (r
−2) to scaling with perimeter (r
−1) when the electrode radius falls below 10 µm. This effect can be explained by the transition from planar to spherical diffusion behavior previously reported for electrochemical microelectrodes. Significance. These results provide important intuition for designing small, single unit recording electrodes. Specifically, for materials where the impedance is dominated by a pseudo-capacitance that is associated with a diffusion limited process, the total impedance will scale with perimeter rather than area when the electrode size becomes comparable with the diffusion layer thickness. For Pt electrodes this transition occurs around 10 µm radius electrodes. At even lower frequencies (1 Hz) impedance approaches a constant. This transition to r
−1 scaling implies that electrodes with a pseudo-capacitance can be made smaller than one might expect before thermal noise or voltage division limits the ability to acquire high-quality single-unit recordings.
