| 1 | A micromirror array with annular partitioning for high-speed random-access axial focusing显示文摘Dynamic axial focusing functionality has recently experienced widespread incorporation in microscopy,augmented/virtual reality(AR/VR),adaptive optics and material processing.However,the limitations of existing varifocal tools continue to beset the performance capabilities and operating overhead of the optical systems that mobilize such functionality.The varifocal tools that are the least burdensome to operate(e.g.liquid crystal,elastomeric or optofluidic lenses)suffer from low(≈100 Hz)refresh rates.Conversely,the fastest devices sacrifice either critical capabilities such as their dwelling capacity(e.g.acoustic gradient lenses or monolithic micromechanical mirrors)or low operating overhead(e.g.deformable mirrors).Here,we present a general-purpose random-access axial focusing device that bridges these previously conflicting features of high speed,dwelling capacity and lightweight drive by employing lowrigidity micromirrors that exploit the robustness of defocusing phase profiles.Geometrically,the device consists of an 8.2mm diameter array of piston-motion and 48-μm-pitch micromirror pixels that provide 2πphase shifting for wavelengths shorter than 1100 nm with 10-90% settling in 64.8μs(i.e.,15.44 kHz refresh rate).The pixels are electrically partitioned into 32 rings for a driving scheme that enables phase-wrapped operation with circular symmetry and requires<30 V per channel.Optical experiments demonstrated the array’s wide focusing range with a measured ability to target 29 distinct resolvable depth planes.Overall,the features of the proposed array offer the potential for compact,straightforward methods of tackling bottlenecked applications,including high-throughput single-cell targeting in neurobiology and the delivery of dense 3D visual information in AR/VR. | Nathan Tessema Ersumo Cem Yalcin Nick Antipa Nicolas Pegard Laura Waller Daniel Lopez Rikky Muller | 2020 | Light(Science & Applications)2020，9，1： | 2 |
| 2 | 炭黑对动态性能的影响显示文摘尽管在几世纪前就发现了天然橡胶,但直到150年前才开始少量应用天然橡胶。使用者发现,固态天然橡胶很难操作。而且,由天然橡胶制成的制品在热天发粘,冷天变硬。十九世纪的两大技术发展解决了这些问题,并为聚合物工业奠定了基础。1820年,Thomas Hancock发明了能够塑化。 | Rikki Lamba 黄祖长 | 2000 | 橡胶参考资料2000，30，8： | 1 |
