Background Flow diverters are used for the treatment of intracranial aneurysms. Surface modification may decrease the thrombogenicity of flow diverters but the details are unknown. Optical coherence ...

Optical neural networks implemented with Mach-Zehnder Interferometer (MZI) arrays are a promising solution to enable fast and energy-efficient machine learning inference, yet finding a practical ...

Co-packaged optics (CPO) is a new technology that provides a cost and power advantage over using DSP based pluggable optical modules in large data center and AI applications. Silicon photonic PICs are ...

Large-scale optical programmable logic array for two-dimensional cellular automata. Credit: Wenkai Zhang (Huazhong University of Science and Technology), edited Optical computing aims to replace ...

Purpose To analyse retinal and choroidal microvasculature features in healthy pregnant women using optical coherence tomography angiography (OCTA). Methods PubMed, Embase, Ovid, Web of Science and ...

Abstract: We propose an all-optical phase comparator for phase noise-tolerant carrier phase recovery of QPSK signals. Our scheme, based on the 2 nd-order phase sensitive amplifier, successfully ...

Artificial intelligence (AI) models have been validated for recognizing signs of eye diseases in retinal images, enhancing diagnosis, and risk stratification. Combining natural images and medical data ...

This is a DIY digital optical comparator, which is an instrument used to take precise measurements of physical objects through visual means. Optical comparators cost tens of thousands of dollars, but ...

Over the past 30 years, physical optics has been enriched by the appearance of singular optics as a new branch approved in scientific classifiers. This review briefly outlines the main concepts of the ...

Abstract: This letter presents a low-loss, dual-polarized, easy-manufacturing, and wideband one-dimension al (1-D) quasi-optical comparator at terahertz (THz) frequencies. A novel comparator structure ...
