光像测定器

The measuring device is structured by including a He-Ne laser; a beam expander, a soft aperture slot and a off-axis parabolic mirror to be measured are arranged in turn along the direction of the emergent laser beam direction of the He-Ne laser; a standard cross hair and a micro objective are arranged in turn on the direction of the reflected beam of the off-axis parabolic mirror; the micro objective is arranged on the focus of the off-axis parabolic mirror; the focus is imaged on an area array CCD; the output end of the area array CCD is connected with a computer; the off-axis parabolic mirror is fixed on a five-dimensional electric adjusting frame.

一种离轴抛物面镜点聚焦能力测定装置和测定方法，测定装置的构成包括：一台He-Ne激光器，沿该He-Ne激光出射激光束方向依次设置扩束器、软边光阑和待测的离轴抛物面镜，在该离轴抛物面镜的反射光束方向依次设置标准叉丝和显微物镜，该显微物镜位于所述的离轴抛物面镜的焦点，所述的焦点成像于面阵CCD上，该面阵CCD的输出端接计算机，所述的离轴抛物面镜固定在一五维电动调整架上。

Under the excitation of 488 nm light beam of argon ion laser source, single suprahelical species could be observed with the aid of a common microscope due to the strong scattered light emitted by the suprahelical species. By capturing the RLS images of the single suprahelical species with a cooled charge coupled device camera, and analyzing the RLS data, herein an RLS imaging method of DNA was proposed based on the linear relationship between the counts of suprahelical species in the detection focus plane and the concentration of DNA in nanograms.

在488nm 氩离子激光光源的激发下，单个超螺旋聚集体的散射光可以通过普通显微镜观察到，用冷却型电荷耦合器对此单个粒子的RLS信号进行成像和分析，发现在聚焦平面上检测到的超螺旋粒子的个数与溶液中纳克级的DNA浓度成正比，基于此建立了一种测定DNA的方法。
