High-speed 3D measurement is receiving increasing attention, but it’s difficult to achieve high efficiency, robustness and reconstructing ratio: https://ow.ly/NHYz50S2tiN This Optics Express [#OPG_OpEx] study proposes a dynamic phase-differencing profilometry to directly resolve the phase difference between the object on the reference plane and the reference plane and improve computational efficiency. The research team’s method also achieves high algorithmic robustness and reconstruction ratio with applications in high-speed 3D measurement.

In dual-function radar communications (#DFRC), the radar receiver output will show multiple peaks representing the different targets' ranges. Each peak comes with surrounding side lobes called #range #side #lobes (#RSLs). Since a different signal is used each time instead of the same one, the peaks and RSLs do not stay synchronized, making it difficult to determine Doppler shift and suppress clutter. The authors propose two new closed-form algorithms for designing DFRC receive filters that ensure synchronization across several signals while also suppressing the RSLs. ---- Muhammad Zubair More details can be found at this link: https://lnkd.in/gCNFihnJ

In this paper, the #time-#modulated #array is combined with the relatively recent #coding-#metasurface #theory to introduce #time-#coding #metasurface #antenna. This innovative antenna design facilitates flexible spatial modulation of #electromagnetic (#EM) wave without using complicated feeding network and traditional phase shifter. Hence, it enables the generation of #multiple #concurrent but #independent #directive #high #gain #beams to cover a predefined angular range, unlike the conventional array antenna which has their single directive beam which covers only one user at cellular communication. The paper focuses on the theoretical analysis of a time-coding metasurface antenna designed with embedded 2-bit PIN diodes, which is successfully fabricated, also. Applying various time sequences, the proposed array showcases the ability to steer beams at the center frequency and concurrently generate multiple beams at different frequencies, each with specific radiation angles. The flexibility and capability of the proposed metasurface antenna candidates it for different communication applications. ---- Morteza Nadi, Ahmad Cheldavi, Seyed Hassan Sedighy More details can be found at this link: https://lnkd.in/eV8HbFmr

What to Expect? RF device testing sometimes requires separate Vector Network Analyzer (VNA) and Vector Signal Transceiver (VST) measurement stations, or a single setup with both VNA and VST instruments.    • Simplify, reduce test costs and learn the benefits of combining the new PXIe-5633 VNA with the PXIe-5842 VST into a single instrument to perform single-connection modulated and S-parameter tests.  • Experience the seamless software workflow and efficiency of using RFmx and InstrumentStudioTM software to program and debug tests. https://lnkd.in/gFCwskrg #ni #testsystems #ate #rftest

Optical module enhances satellite lens versatility Resolve Optics has developed a unique optical module that fulfils the wide range of mounting arrangements used by different satellite camera systems. Developed in conjunction with ultra-high-definition video camera specialists – Sen (London, UK), the new 406-000 f2 radiation resistant lens from RESOLVE OPTICS LIMITED is incorporated within an optical module which can easily be removed and secured in a wide variety of different mounts. Rob Watkinson, sales manager at Resolve Optics said “Our new optical module system provides Sen with the flexibility to use the same high-performance video camera lens no matter which partner they decide to launch with. Offering a focal length of 75mm the new 406-000 is the latest addition to the growing range of lenses we have developed for Sen to cover a variety of GSD (ground sampling distance) applications. Previous lenses supplied to Sen have already been deployed into space and are generating amazing 4K images of the Earth and Space”. https://lnkd.in/e75_Tmk2 #news #pr #magazine #advertising #b2b #bannerads #magazine #newsletter #emailcampaigns #engineering #manufacturing #automation

#Stacked #intelligent #metasurfaces (#SIM) are an emerging programmable metasurface architecture that can directly process signals in the electromagnetic wave domain. This enables efficient #ultra-#massive #MIMO transceivers to be implemented with a limited number of #radio #frequency (#RF) chains. #Channel #estimation (#CE) is challenging for SIM communication systems because of the large channel dimensions and only a few RF chains. To efficiently solve this, the authors developed a novel #hybrid #digital-#wave #domain #channel #estimator. The received training symbols are first processed in the wave domain within the SIM layers. The wave domain channel estimator, parameterized by the phase shifts applied by the meta-atoms in all layers, is optimized to minimize the mean squared error (MSE) using a gradient descent algorithm. This high accuracy is achieved with a training overhead that can be reduced by exploiting potential low rank channel correlation matrices. ---- Qurrat-Ul-Ain Nadeem, Jiancheng An, Anas Chaaban More details can be found at this link: https://lnkd.in/g7ZgJJ75
