SWIR imaging and space applications

  1. 1. 1 1 Impasse de la Noisette Verrières le Buisson 91370 FRANCE SWIR imaging and space applications 11/09/2019 Simon Ferré simon.ferre@new-imaging-technologies.com
  2. 2. 2‹#› 80% EXPORT 22 EMPLOYEES BASED IN PARIS Visible and SWIR SENSORS,CAMERAS AND MODULES WDR SOLUTIONS IN VISIBLE AND SWIR 15 YEARS OF RESEARCH >20 PATENTS COMPANY OVERVIEW 22
  3. 3. 3 New Space Defense SurveillanceScientific Machine Vision MARKETS AND CUSTOMER INTEGRATIONS
  4. 4. 4 CORE TECHNOLOGY – HDR PIXEL IN PIXEL HDR : 140dB – NO SATURATION SINGLE EXPOSURE FITS ALL LIGHTING SITUATIONS EXTREMELY SIMPLE CONTROLS AND SETTINGS (no cooling system) Illustration High Dynamic range from pixels 4
  5. 5. Present and future SWIR sensors QVGA & VGA LineScan 1.3 Mpixels ▪ 1280 x 1024/ 10x10µm² ▪ 320 x 256 / 640 x 512 ▪ 25x25µm² / 15x15µm² ▪ 2048 >60Khz /7.5µm²/7.5x200µm² 2017 2019 2020 InGaAs SWIR: 900 – 1700 nm 5
  6. 6. OUR PRODUCTS FOR YOUR APPLICATION WiDy SWIR ▪ VGA and QVGA (HDR) ▪ Gated Imaging option ▪ Cost effective solutions WiDy SenS ▪ VGA ▪ High Sensitivity and HDR ▪ Gated Imaging option ▪ SWIR imaging swiss-knife WiDy Nano ▪ VGA (HDR) ▪ HDR 120dB ▪ Miniature size 6
  7. 7. SWIR applications for new space Three typical and future use cases Space optical telecommunications (TRL 6-8) Cooled cameras for Astronomy (TRL 4-6) Hyperspectral SWIR cameras for earth monitoring (TRL 3-5) 7
  8. 8. Use case 1 – spatial optical telecommunications 8 • Radio frequency link • Laser-based optical link Power efficient More secure information (beam waist /1000-20000) High speed (x100-300) Lower SWaP No license Requirements High frame rate (230-5000fps) High sensitivity High dynamic (120 dB) Cost-effective Short lead time OSA-OPN
  9. 9. USE CASE 2 - Astronomy • Needs – Very long exposure time (>> 1sec) – Low dark current and readout noise – Cooling capabilities – Acceptable SWaP • What we propose – Cooling capabilities flexibility • Single/double Peltier cooled • Cryogenic cooled – High performances – Advantages of SWIR (higher transmission throught the atmosphere, …) – Cost-effective solutions Parameter Value ΔT 60°C/150°C Dark Current @ -40°C <200°e-/sec Frame rate 230 fps Mode NDRO / Linear / Log Exposure time >> 1min Size ~ H55 x W75 x L140 mm 9
  10. 10. DEEP COOLED INGAAS CAMERA images 10 Jupiter (H band filter: 1475-1700nm) Saturn rings in SWIR (J band filter: 1100-1325nm) Same image with contrast reversed and stretched
  11. 11. Use case 3 – hyperspectral earth mapping First approach: Linear Variable Filter (LVF) 0 0.2 0.4 0.6 0.8 1 1100 1300 1500 1700 Normalizedspectral response lambda (nm) • Many applications in earth monitoring – Smart agriculture – Mineral ressources prospect – Fire fighting – Pollution surveillance • Statement: hyperspectral cameras are not very space friendly – Optical and mechanical complexity – Bulky, fragile and expensive 11 ESA
  12. 12. Use case 3 – hyperspectral earth mapping Second approach: Fabry Pérot Interferometer (FPI) • For snapshot 2D imaging • Scanning from 1100nm to 1600 nm • 25 wavelengths/seconds • On drone tests to be led late 2019 12 Camera Lens PFPI
  13. 13. Conclusion • What we can offer: SWIR camera and sensors – HDR and high sensitivity – Fast framerate – Active imaging mode – Cost-effective solution – Short lead time • What we are looking for (thank to EPIC!): – Market and field feedbacks – Partnerships 13
