Weave是西班牙加那利群岛拉帕尔马的威廉·赫歇尔望远镜(WHT)的下一代广域光学光谱设备。这是一个多目标“拾取和放置”光纤馈电光谱仪，在一个新的专用2°主焦校正器后面有1000多根光纤，这在概念上类似于澳大利亚天文台的2DF仪器1，有两个观察板，一个是观测天空，另一个是由机器人纤维定位器重新配置。它将能够在一夜之间获取超过10000颗恒星或星系的光谱。织造定位器的概念使用两个机器人协同工作，以便在仪器预期的1小时停留时间内重新配置完全填充的场地(由于差异折射的影响，所需曝光时间与给定配置的有效性限制之间的良好匹配)。
WEAVE is the next-generation wide-field optical spectroscopy facility for the William Herschel Telescope (WHT) in La Palma, Canary Islands, Spain. It is a multi-object "pick and place" fibre fed spectrograph with more than one thousand fibres behind a new dedicated 2° prime focus corrector, This is similar in concept to the Australian Astronomical Observatory's 2dF instrument1 with two observing plates, one of which is observing the sky while other is being reconfigured by a robotic fibre positioner. It will be capable of acquiring more than 10000 star or galaxy spectra a night. The WEAVE positioner concept uses two robots working in tandem in order to reconfigure a fully populated field within the expected 1 hour dwell-time for the instrument (a good match between the required exposure times and the limit of validity for a given configuration due to the effects of differential refraction).
