Description: Compressive Sensing is an unconventional approach to acquiring and re-constructing data from space. The technique could significantly improve how efficiently data collected in space is processed and sent down to the ground, as well as enabling instruments to be smaller and lighter than their traditional counterparts. Compressive Sensing could have many space applications, including in imaging instruments for Earth observation, planetary exploration and space science. This image shows the design for an optical instrument adopting technology used for Compressive Sensing.
