Terahertz sensor aiming for Jupiter´s moons



A high performance terahertz receiver aiming for space missions such as ESA’s “Jupiter icy moons explorer” has been developed in a joint European effort, led by Chalmers University of Technology.

Remote analysis of gases and vapours by heterodyne spectroscopy is a powerful tool in environmental monitoring, astronomy, and planetary research. Particularly for space applications, compact, light-weight and robust heterodyne spectrometers are necessary.

In a joint European effort, researchers have developed a heterodyne receiver which satisfies the requirements set by space missions. This is achieved by minimising the number of components in the local oscillator (LO) of the receiver, and by a high degree of integration of all of its subcomponents.
