Optik 2025年 327卷

Fringe projection profilometry (FPP) has the advantages of large field of view, high precision and resolution, and is widely used in industrial inspection, medical treatment, aerospace and other fields. The nonlinear response between the camera and the projector in the system will affect the sinusoidal intensity of the captured fringe images, produce periodic phase errors, and affect the final reconstruction accuracy. Traditional double N-step phase shift (NPS) and Hilbert transform (HT) methods only correct the fundamental harmonic part of the phase nonlinear errors, and ignore the rest of the higher harmonic. Therefore, a double HTs based nonlinear phase error correction method is proposed, taking the higher order nonlinear harmonics into account. The artificial sinusoidal fringe images without background term are constructed using the wrapped phase calculated by captured fringe images. Then the HT is performed to convert the phase error to multiplication from addition, which can realize error balance in phase calculation. After obtaining the new phase, reoperation of artificial fringe generation and HT (AHT) is carried out to effectively remove the high order harmonic part of nonlinear harmonics. In proposed method, the wrapped phase calculated by captured fringe images is directly used to generate the artificial fringe images, which does not require additional projection patterns and realize real-time correction of phase nonlinear errors with high accuracy. Furthermore, direct artificial fringe generation also can efficiently avoids the effect of background intensity to the HT. Theoretical analysis, simulation analysis and experimental verification all prove the feasibility and superiority of the proposed method. © 2025 Elsevier GmbH

Small materials with pliability and untethered mobility are particularly suitable for minimally invasive medical interventions inside the body. However, the capabilities and applicability of such soft ‘robots’ are restricted by foreign-body responses to them and by the need to get them cleared from the body after the intervention. Here we report the development of biodegradable magnetized biohybrid blood hydrogel fibres that evade immune recognition, and their applicability for targeted intracranial tumour therapy with real-time tracking through X-ray fluoroscopy. The gel fibres can be made of the patient’s own blood mixed with a small amount of magnetic particles and can be produced in about 15 min. We show that the locomotion of intracranially injected gel fibres through cerebrospinal fluid can be remotely controlled under a magnetic field and fluoroscopically tracked, and that a drug encapsulated in the gels can be released on demand under magnetic control, as we show for the delivery of doxorubicin to intracranial tumours in the minipigs. Biodegradable soft actuatable materials that avoid foreign-body responses may aid the development of personalized targeted interventions. © The Author(s), under exclusive licence to Springer Nature Limited 2025.

Optimal strategy of searching FPD weights scanning matrix using GA-PSO

引用

Journal of Shanghai University(English Edition) 2011年第4期15卷 292-296页

作者：严利民顾裕灿李建东 Key Laboratory of Advanced Display and System Application (Shanghai University) Ministry of Education

This paper discusses a kind of optimal method used for searching flat panel display （FPD） scanning matrix. The method adopts bionic algorithm： genetic algorithm （GA） and particle swarm optimization （PSO） algorithm. The method using single GA is more time-consuming, and the search efficiency is low in later evolution; the PSO algorithm is easily falling into the local optimal solution and appears the premature convergent phenomenon. Hence, a hybrid approach of GAPSO is found to optimize the search for high grayscale weights scanning matrix. Finally in the acceptable time, it finds a weight scanning matrix （WSM） of 256 gray scales with Matlab, whose scanning efficiency reaches 94.73% and the linearity is very good.

Journal of Shanghai University(English Edition) 2011年第4期15卷 242-244页

作者：石继锋陈龙龙李倩李喜峰张建华 Key Laboratory of Advanced Display and System Application (Shanghai University) Ministry of Education

Amorphous InGaZnO （a-IGZO） films were deposited on the corning eagle XG （EXG） glass substrates using magnetron sputtering method. The structure, surface morphology, electrical and optical properties of these films were investigated by X-ray diffraction （XRD）, scanning electron microscopy （SEM）, semiconductor parameter analyzer and ＇spectrophotometry, respectively. The influence of oxygen flow on the electrical properties of IGZO thin films was studied, showing that increasing oxygen flow changes the resistivity with six orders of magnitude. The contact resistance of ITO/IGZO is 7.35×10^-2 Ω-cm2, which suggests that a good ohmic contact exists between In2O3 ： Sn （ITO） and IGZO film.

Effect of annealing on wet etch of amorphous IGZO thin film

引用

Journal of Shanghai University(English Edition) 2011年第4期15卷 245-247页

作者：陈龙龙石继锋李倩李喜峰张建华 Key Laboratory of Advanced Display and System Application (Shanghai University) Ministry of Education

Amorphous InGaZnO （a-IGZO） film is deposited on the glass substrate by radio-frequency sputtering and the influence of annealing on wet etch of a-IGZO films were investigated. The results show that etch rate of IGZO films decrease with the increase of annealing temperature. Etching taper angle is less than 60° and critical dimension （CD） loss is less than 1μm in over-etching time of 30 s. The fact implies that IGZO films etching with oxalic acid may be a good wet etching way for the thin-film transistor （TFT） array process.

Top-emitting organic light-emitting diodes (TEOLEDs) based on metal/transparent conductive oxide composite anodes, which were Al/ITO and Ag/ITO, were studied. The microcavity effect was optimized by adjusting the microcavity thickness and microcavity order to achieve high color gamut RGB monochromatic light display. Through mathematical modeling and spectral simulation, TEOLEDs with different microcavity structures were designed. The results showed that the full width at half maximum and the color purity of the light of the TEOLED based on the second-order microcavity were significantly optimized compared to those of the TEOLED based on the first-order microcavity. Meanwhile, the TEOLEDs based on the Ag/ITO composite electrode exhibited better optoelectronic performance, with the significantly enhanced external quantum efficiency of up to 19.40%, narrower full width at half maximum of down to 20 nm, and improved color purity. The corresponding red, green, and blue TEOLEDs had achieved excellent color coordinates of (0.697, 0.301), (0.154, 0.769), and (0.139, 0.050), and the color gamut area of the device had reached 172.4% of the color gamut area of the bottom-emitting OLED, 125.6% of the National Television system Committee standard color gamut, and 93.8% of the ITU-R Recommendation BT.2020 standard color gamut. © 2025, The Authors.

A lightweight model for long-term multivariate time series forecasting via high-dimensional feature maps

引用

Applied Soft Computing 2025年 178卷

作者： Shixiang Tang Yepeng Guan School of Communication and Information Engineering Shanghai University Shanghai 200444 China Key Laboratory of Advanced Display and System Application Ministry of Education Shanghai 200072 China Key Laboratory of Silicate Cultural Relics Conservation (Shanghai University) Ministry of Education Shanghai 200444 China

In practical applications, both performance and computational cost are crucial for long-term time series forecasting (LTSF). Transformers excel in capturing long-sequence interactions but suffer from slow training and high computational demands, limiting timely predictions. On the other hand, lightweight linear models often lack accuracy. These challenges may arise from the limited representational capacity of time series in their one-dimensional (1D) form. To address these limitations, TSMNet, a novel lightweight model, is proposed. TSMNet decouples the time series into higher dimensions, significantly enhancing feature representation efficiency while avoiding information redundancy. By segmenting 1D time series into multiple time series maps (TSMs) and employing periodic feature mixing and sub-TSM stacking strategies, local dependencies and global correlations are captured simultaneously. Additionally, an encoder based on two-dimensional (2D) dilated convolutions is introduced, with expandable channels and progressively widening convolutional kernels, enabling the comprehensive extraction of complex temporal variations. Finally, the extracted features are efficiently decoded and predicted via a multilayer perceptron (MLP) flatten head. Experiments on ten benchmark long-term time series forecasting datasets demonstrate that TSMNet achieves relative improvements of 8.40% compared with the state-of-the-art (SOTA) method. Furthermore, TSMNet operates approximately 10–41 times faster with extremely low computational resources.

Efficiency enhancement in DIBSQ：PC71BM organic photovoltaic cells by using Liq-doped Bphen as a cathode buffer layer

引用

Frontiers of Materials Science 2017年第3期11卷 233-240页

作者： Guo CHEN Changfeng SI Pengpeng ZHANG Kunping GUO Saihu PAN Wenqing ZHU Bin WEI Key Laboratory of Advanced Display and System Applications (Ministry of Education) Shanghai University Shanghai 200072 China

We have improved the photovoltaic performance of 2,4-bis[4-（N,N- diisobutylamino）-2,6-dihydroxyphenyl] squaraine：[6,6]-phenyl C71-butyric acid methyl ester （DIBSQ：PC71BM） organic photovoltaic （OPV） cells via incorporating Liq-doped Bphen （Bphen-Liq） as a cathode buffer layer （CBL）. Based on the Bphen-Liq CBL, a DIBSQ：PC71BM OPV cell possessed an optimal power conversion efficiency of 4.90%, which was 13% and 60% higher than those of the devices with neat Bphen as CBL and without CBL, respectively. The enhancement of the device performance could be attributed to the enhanced electron mobility and improved electrode/active layer contact and thus the improved photocurrent extraction by incorporating the Bphen-Liq CBL. Light-intensity dependent device performance analysis indicates that the incorporating of the Bphen-Liq CBL can remarkably improve the charge transport of the DIBSQ：PC71BM OPV cell and thus decrease the recombination losses of the device, resulting in enhanced device performance. Our finding indicates that the doped Bphen-Liq CBL has great potential for high-performance solution-processed small-molecule OPVs.
