并行STED显微术的新范例

A new paradigm for parallelized STED microscopy

Omer Wagner, Ori Cheshnovsky, Yael Roichman

摘要:

我们提出了一种新的设计多色,并行STED显微镜,能够多光束扫描。我们的设计是基于一个共同的可编程衍射光学元件,用于分裂,形状,并调整激发光束以及耗尽光束,和一个CCD相机的图像荧光从所有扫描光束同时。在这里,我们描述了一个原型实现的双光束STED基于我们的新设计,这可以很容易地推广到多色STED,与多达100个平行扫描光束给予足够的激光功率,和高速率STED成像与使用的高速响应多阳极光电倍增管检测器。

英文摘要:

We propose a new design for a multi-color, parallelized STED microscope, capable of multiple beam scanning. Our design is based on a common programmable diffracting optical element used to split, shape, and align both the excitation beams as well as the depletion beams, and a CCD camera to image florescence from all scanning beams simultaneously. Here we describe a prototype implementation of a two beam STED based on our novel design, which could easily be generalized to multi-color STED, with up to 100 parallel scanning beams given enough laser power, and high rate STED imaging with the use of a high-speed response multianode photomultiplier detector.
