Abstract

Programmable diffraction gratings show new functionalities for future space instruments, including spectrometers, wideband sharp-edge filters or dichroiumlc plates with fully adjustable transmission. Successful implementation in Darwin-like mission has been demonstrated on a breadboard. Exo-planet spectra without and with life signatures could be clearly measured.
