论文摘要
我们描述了一种能够高精度（$ 10^{ - 5} $）的新仪器，同时在三个通带（$ bvr $）中同时观察。该仪器利用电子型EM CCD摄像机来高效效率和快速图像读数。 Dipol-uf的关键特征是：（i）具有较高吞吐量和固有稳定性的光学设计； （ii）多功能性使该仪器最适合观察明亮和微弱的目标； （iii）控制系统，该系统允许远程使用偏光仪。示例是从高度的信噪比观察到附近明亮的恒星和静态二进制诸如X射线二进制量的静物状态下获得的第一个结果。
We describe a new instrument capable of high precision ($10^{-5}$) polarimetric observations simultaneously in three passbands ($BVR$). The instrument utilizes electron-multiplied EM CCD cameras for high efficiency and fast image readout. The key features of DIPol-UF are: (i) optical design with high throughput and inherent stability; (ii) great versatility which makes the instrument optimally suitable for observations of bright and faint targets; (iii) control system which allows using the polarimeter remotely. Examples are given of the first results obtained from high signal-to-noise observations of bright nearby stars and of fainter sources such as X-ray binaries in their quiescent states
