Qinetiq awarded ESA contract

Instruments used on spacecraft, such as atmospheric sensors for improving weather forecasting and monitoring climate change, could become smaller and more lightweight following the award of a contract to

.

Scientists at Qinetiq’s Optronics Centre will develop its patented hollow waveguide (HWG) optical integration technology for use in optical space instrumentation, with the aim of improving the performance and reliability of space sensors and reducing their costs.

The European Space Agency (ESA) has awarded Qinetiq a €310,000 contract to develop two demonstrator systems in order to assess the potential of the technology for space missions. Optical systems for micro-satellites are an area of initial interest, but hollow waveguide optical integration technology could be used in a wide range of sensors for earth observation, planetary exploration, atmospheric sensing and optical communications.

In Qinetiq’s approach, hollow waveguides are used to guide light through a circuit of optical components located in a common substrate. The hollow waveguide channels and the alignment slots that the components are located in are formed in the surface of the substrate using either milling or etching techniques. In the same way that copper tracks carry electrons around an electronic printed circuit board (PCB), the hollow waveguides guide light between the optical components. The approach has the potential to simplify and speed manufacture, reduce mass and volume and to improve performance, particularly in harsh environmental conditions.
