In this framework, we are studying different approaches based on the compressive sampling technique supported by innovative multispectral detectors, where the image sampling is performed on the telescope focal plane with a Digital Micromirror Device (DMD). We will describe in the paper the possibilities and the constraints given by the use of the DMD in the focal plane. The optical design of the telescope, relay system and detector in two different application cases will be provided.ELETTRONICOenConference paper10.1117/12.23120082-s2.0-85054820103000450864600144https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10698/2312008/Compressive-sampling-for-multispectral-imaging-in-the-vis-NIR-TIR/10.1117/12.2312008.short2018SPIE10698E..5OPFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_17 Instrumentation – telescopes, detectors and techniques
