Mechanical-scan-free multicolor super-resolution imaging with diffractive spot array illumination

Autor: Ning Xu, Sarah E. Bohndiek, Zexing Li, Cilong Zhang, Qiaofeng Tan

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-11 (2024)

Abstract Point-scanning microscopy approaches are transforming super-resolution imaging. Despite achieving parallel high-speed imaging using multifocal techniques, efficient multicolor imaging methods with high-quality illumination are currently lack

Copula-based modeling of hydraulic structures using a nonlinear reservoir model

Autor: Qiaofeng Tan, Yunze Mao, Xin Wen, Tian Jin, Ziyu Ding, Zhenni Wang

Publikováno v: Hydrology Research, Vol 52, Iss 6, Pp 1577-1595 (2021)

Multivariate flood frequency analysis has been widely used in the design and risk assessment of hydraulic structures. However, analytical solutions are often obtained based on an idealized linear reservoir model in which a linear routing process is a

Axial Multifocus Beams Formed by Binary Optical Elements

Autor: Ning Xu, Huan Xiao, Zhe Kong, Qiaofeng Tan

Publikováno v: IEEE Photonics Journal, Vol 11, Iss 2, Pp 1-10 (2019)

Axial multifocus beams (AMBs) potentially offer convenience in scientific and industrial applications. However, the general approach used for forming AMBs based on the Fresnel zone plate limits the conceivable applications. In this paper, we introduc

Fluorescence Enhanced Optical Resonator Constituted of Quantum Dots and Thin Film Resonant Cavity for High-Efficiency Reflective Color Filter

Autor: Xiaochuan Chen, Pengxia Liang, Qian Wu, Qiaofeng Tan, Xue Dong

Publikováno v: Nanomaterials, Vol 11, Iss 11, p 2813 (2021)

Conventional color filters selectively absorb a part of the backlight while reflecting or transmitting other light, resulting in the problem of low efficiency and energy wasting. For this problem, a new concept of fluorescence enhanced optical resona

A Hybrid Diffractive Optical Element Design Algorithm Combining Particle Swarm Optimization and a Simulated Annealing Algorithm

Autor: Ping Su, Chao Cai, Yuming Song, Jianshe Ma, Qiaofeng Tan

Publikováno v: Applied Sciences, Vol 10, Iss 16, p 5485 (2020)

With the rapid development of computer hardware and the emergence of the parallel calculation of diffraction fields, a breakthrough has been made in terms of the limitation of the unacceptable amount of computational cost to design diffractive optica
