Dedicated accelerometers have been developed for the MICROSCOPE mission taking into account the specific range of acceleration to be measured on board the satellite. Considering one micro-g and even less as the full range of the instrument, leads to a customized concept and a high performance electronics for the sensing and servo-actuations of the accelerometer test-masses. In addition to a very accurate geometrical sensor core, a high performance electronics architecture provides the measurement of the weak electrostatic forces and torques applied to the test-masses. A set of capacitive sensors delivers the position and the attitude of the test-mass with respect to a very steady gold coated cage made in silica. The voltages applied on the electrodes surrounding each test-mass are finely controlled to generate the adequate electrical field and so the electrostatic pressures on the test-mass. This field maintains the test-mass motionless with respect to the instrument structure. Digital control laws are implemented in order to enable instrument operation flexibility and a weak position sensor noise. These electronics provide both the scientific data for MICROSCOPE's test of General Relativity and the data for the satellite drag-free and attitude control system (DFACS).
Modern Microscopy with the Web of Things: The OpenFlexure Microscope Software Stack
科学仪器的自动化和计算机化控制在现代实验室中几乎无处不在。大多数仪器都是通过几十年前的通信总线控制的，或者通过专有的系统库访问。这限制了哪些语言和操作系统可用于控制仪器，并在将多个仪器连接到同一实验中时造成了重大问题。在此，我们以OpenFlexure显微镜软件栈为例，说明如何使用现有的、跨平台的、独立于语言的、行业支持的标准来控制科学仪器。我们将控制代码分为客户端和服务器应用程序，通过符合W3C Web of Things标准的Web API进行接口。这使得可以通过多种语言简单地控制显微镜，提供现代化的图形控制界面，并最大限度地减少重复代码。网络控制还使软件栈更强大，允许一台计算机控制多个显微镜，并促进本地或远程用户之间的设备共享。在研究实验室中使用物联网方法有可能解决实验集成的许多关键挑战，使用已经成熟的技术。
