标题： Characterisation of the signal to noise ratio of 2-photon microscopes

摘要： 信噪比（SNR）是成像仪器的关键性能指标。 在这里，我们描述了定制的双光子显微镜的SNR特性，并将我们显微镜的SNR性能与选定的商用双光子显微镜进行比较。 本文描述的方法可以为希望对其双光子或其他点扫描显微镜进行特性和基准测试的其他人提供指导。 显示英文摘要

摘要： Signal to noise ratio (SNR) is a key performance metric of an imaging instrument. Here we describe characterisation of SNR of a custom 2-photon microscope and compare the SNR performance of our microscope with selected commercial 2-photon microscopes. The methodology described in this paper can serve as guidance for others wishing to characterise and benchmark their 2-photon or other point-scanning microscopes.
