Demonstrate a multipoint temperature sensor network based on optical fiber sensor techniques suitable to achieve micro kelvin resolution temperature measurements that would be suitable for science missions such as LISA.An increasing number of scientific missions are relying on the extreme levels of thermal control in order to perform their scientific goals. For example LISA requires micro-Kelvin resolution temperature knowledge of the space craft in order for the payload to achieve its primary mission. This level of performance is currently not possible with existing electrical gauges. Fibre optic techniques can offer some substantial benefits not only offering a means to achieve these levels of performance but also providing additional benefits such as electromagnetic interference (EMI) immunity, galvanic isolation and the possibilities in some configurations to offer multiplexing of sensors along the sensing fiber, either in a truly distributed approach or quasi distributed, using elements such as Bragg gratings.1)To design and manufacture an Elegant Breadboard Model of the MeasurementSystem as well as a Test Bench for performance testingachieving Technology Readiness Level (TRL) 4.2)To carry out performance testing of the developed Measurement System and exploit the results,3) To define the necessary steps in order to take the Elegant Breadboard Model to a TRL 6.
