  1. Fresnel Diffractive Arrays Imagery Sky observation Targets Presented by Truswin Raksasataya

  2. Agenda • Sky validation and its objectives • FDAI Gen II configurations • FDAI Gen II Estimation • First Results • Future Targets

  3. Sky observation for Prototype II • To test Fresnel Imagery with real astrophysical objects. • To validate the performance of Fresnel Imagery with the ground support of 20 meter long focal • To test the operation on field usages.

  4. What’s changes • Prototype Gen II and Current state • Version 1.5.1 • What’s change • But.. • Effective area is approximately the same as Prototype 1, Chromatic Correction

  5. Recent Results from Sky observation • FDAI 1.5.1 No Tilt tip compensation for atmosphere turbulance

  6. Estimation of Fresnel Dynamic Range

  7. First Results from Sky observation Fresnel Imagery version 1.5.1 during transferred state: Single Stars Vega : Magnitude: 0

  8. Recent Results from Sky observation • Single Star : Deneb • Magintude: 1 From FDAI 1.5.1

  9. Recent Results from Sky observation • Epsilon Lyr • ----------------------------------- • Epsilon 1 AB • Magnitude : 1 • Separation 2.6 arcsec • Epsilon 2 AB • Magnitude : 1 • Separation 2.3 arcsec

  10. Recent Results from Sky observation • STT 433 : (Upsilon Cyg) Mag(Separation,arcsec): 4.4, 10(15”), 9,9(21”) STT 433 C STT 433 B STT 433 A

  11. Recent Results from Sky observation • STF 2767 • Magnitude: 4.2, 8.7 • Separation: 6 arcsec B A

  12. Recent Results from Sky observation Epsilon Lyr 1 AB STT 433 Epsilon Lyr 2 AB STF 2767 Results form Ground validation from FDAI 1.5.1

  13. Future Targets • High Dynamic Ranges Targets : Binary systems Double Stars: Sirius AB , Procyon AB , AGC 9AB etc. • Extended Fields: Solar system objects Mars and its satellites : High Resolution image , separation of its satellites. Pluton and Charon: Challenge!

  14. Future Targets • Double Stars Xi Peg BUP 9AB AGC 9AB Procyon AB BU 633AB SiriusAB

  15. Future Targets • Solar system objects • Mars and its Satellites
