  1. A space Fresnel imager conceptWhat features for what Science Additional presentation Preparing the way to space borne Fresnel Imagers Nice Observatory Workshop  September 2009

  2. What features for what Science • This presentation compares different scientific needs with their associated necessary instrument main features • In the next slides, the foreground text color corresponds to the spectral bandwidths: 3 array size classes: 3.5m10m30m IR NIR Vis NUV FUV Fresnel Nice Workshop 24/09/09 Space Fresnel Imager concept Laurent Koechlin and Emmanuel Hinglais

  3. Faraway missions:extragalactic and young universe Scientific need " IR NIR Fresnel Nice Workshop 24/09/09 Space Fresnel Imager concept Laurent Koechlin and Emmanuel Hinglais

  4. Faraway missions:extra galactic and young universe Instrumental consequences Fresnel Nice Workshop 24/09/09 Space Fresnel Imager concept Laurent Koechlin and Emmanuel Hinglais

  5. Mid distance missions:Our galaxy active regions Scientific need " IR Vis UV Fresnel Nice Workshop 24/09/09 Space Fresnel Imager concept Laurent Koechlin and Emmanuel Hinglais

  6. Mid distance missions:Our galaxy active regions Instrumental consequences Fresnel Nice Workshop 24/09/09 Space Fresnel Imager concept Laurent Koechlin and Emmanuel Hinglais

  7. Nearby missions:Stellar and circumstellar imaging Scientific need " UV Vis UV Fresnel Nice Workshop 24/09/09 Space Fresnel Imager concept Laurent Koechlin and Emmanuel Hinglais

  8. Nearby missions:Stellar and circumstellar imaging Instrumental consequences Fresnel Nice Workshop 24/09/09 Space Fresnel Imager concept Laurent Koechlin and Emmanuel Hinglais

  9. Nearby missions:Exoplanets Scientific need Fresnel Nice Workshop 24/09/09 Space Fresnel Imager concept Laurent Koechlin and Emmanuel Hinglais

  10. Nearby missions:Exoplanets Instrumental consequences Fresnel Nice Workshop 24/09/09 Space Fresnel Imager concept Laurent Koechlin and Emmanuel Hinglais

  11. Local missions:Solar system small objects • High resolution imaging • High dynamic range Scientific need Fresnel Nice Workshop 24/09/09 Space Fresnel Imager concept Laurent Koechlin and Emmanuel Hinglais

  12. Local missions:Solar system small objects • High resolution imaging • High dynamic range Instrumental consequences Fresnel Nice Workshop 24/09/09 Space Fresnel Imager concept Laurent Koechlin and Emmanuel Hinglais

  13. Synthesis Only 4 instrumental configurations could cover the full domain • Configuration 1 • 4 m lens, UV band, 3 channels, "low" dynamic range (10-4)covering: - Active regions of our Galaxy - Stellar physics - Solar system Fresnel Nice Workshop 24/09/09 Space Fresnel Imager concept Laurent Koechlin and Emmanuel Hinglais

  14. Synthesis • Configuration 2 10 m lens, UV band, 4 channels, "low" dynamic range (10-4) covering : - Extragalactic - Active regions de la Galaxy - Stellar physics - Solar system Fresnel Nice Workshop 24/09/09 Space Fresnel Imager concept Laurent Koechlin and Emmanuel Hinglais

  15. Synthesis • Configuration 3 10 m lens, IR band, 4 channels, high dynamic range (10-8)Covering: - Extragalactic - Active regions of the Galaxy - Stellar physics - Jovian exoplanets & super-earths - Solar system Fresnel Nice Workshop 24/09/09 Space Fresnel Imager concept Laurent Koechlin and Emmanuel Hinglais

  16. Synthesis • Configuration 4 30 m lens, IR band, 4 channels, high dynamic range (10-8)Covering: - Far universe - Stellar astrophysics - Jovian et telluric exoplanets - Solar system Fresnel Nice Workshop 24/09/09 Space Fresnel Imager concept Laurent Koechlin and Emmanuel Hinglais
