2Deep optics preconditioner for modulation-free pyramid wavefront sensing显示文摘The pyramid wavefront sensor(PWFS)can provide the sensitivity needed for demanding adaptive optics applications,such as imaging exoplanets using the future extremely large telescopes of over 30 m of diameter(D).However,its exquisite sensitivity has a limited linear range of operation,or dynamic range,although it can be extended through the use of beam modulation—despite sacrificing sensitivity and requiring additional optical hardware.Inspired by artificial intelligence techniques,this work proposes to train an optical layer—comprising a passive diffractive element placed at a conjugated Fourier plane of the pyramid prism—to boost the linear response of the pyramid sensor without the need for cumbersome modulation.We develop an end-2-end simulation to train the diffractive element,which acts as an optical preconditioner to the traditional least-square modal phase estimation process.Simulation results with a large range of turbulence conditions show a noticeable improvement in the aberration estimation performance equivalent to over 3λ∕D of modulation when using the optically preconditioned deep PWFS(DPWFS).Experimental results validate the advantages of using the designed optical layer,where the DPWFS can pair the performance of a traditional PWFS with 2λ∕D of modulation.Designing and adding an optical preconditioner to the PWFS is just the tip of the iceberg,since the proposed deep optics methodology can be used for the design of a completely new generation of wavefront sensors that can better fit the demands of sophisticated adaptive optics applications such as ground-to-space and underwater optical communications and imaging through scattering media.FELIPE GUZMÁN JORGE TAPIA CAMILO WEINBERGER NICOLÁS HERNÁNDEZ JORGE BACCA BENOIT NEICHEL ESTEBAN VERA 2024Photonics Research2024,12,2:0

4新英格兰医学中心后循环登记显示文摘在407例新英格兰医学中心后循环登记患者中,59%为不伴TIA的卒中,24%在卒中前有TIA,16%仅表现为TIA。栓塞是最常见的卒中机制(占40%,其中24%为心源性栓塞,14%为动脉-动脉栓塞,2%两者兼有)。在32%的患者中,大动脉闭塞性损害导致血流动力学性脑缺血。梗死最常出现在后循环远段供血区(脑干腹侧、小脑上部以及枕叶和颞叶),近段(延髓和小脑后下部)和中段(桥脑和小脑前下部)供血区受累的比例相当。148例患者存在至少累及1支大动脉的重度闭塞性损害(狭窄〉50%),134例患者有单侧或双侧动脉受累。最常见的闭塞部位是椎动脉颅外段(52例患者,15例双侧)、椎动脉颅内段(40例患者,12例双侧)和基底动脉(46例患者)。动脉-动脉栓塞是椎动脉闭塞性疾病患者最常见的脑梗死发病机制。30d病死率为3.6%。发病机制为栓塞,远段供血区受累和基底动脉闭塞性疾病患者的预后最差。具有多处动脉狭窄部位的患者转归最好。他们通常经年累月地发生TIA。Louis R.
