The Microwave Laboratory is currently supporting technology demonstration tests for the Event Horizon Imager mission concept. The Event Horizon Imager aims at providing a high resolution picture for the black hole’s event horizon shadow leveraging millimetre and sub-millimetre frequency observations from space. The laboratory test objective is to demonstrate the generation of coherent local oscillators at two satellites from their independent master oscillators, this which enables a two satellite system to perform space-to-space very long baseline interferometry. This technique avoids Earth atmospheric disturbances which make impossible any imaging from ground radio telescopes at such high frequencies.
