　　报告题目：Latest Technology and Application in Astronomy

　　报告摘要：Challenges and our innovations

　　PI has worked within space imaging/earth imaging for a long time in China and around the world.

　　1. Long endurance/maintenance free operations:

　　NSSC's Prof. Yuan needs the best scientific camera to use in 35 stations located all across China.Over 50 PI cameras were used for over 10 years.

　　2. NIR etaloningand our eXcelon technology.

　　3. Deep Cooling: How to make deep cooling easy to use and stable for long exposure? ArcTec and SOPHIA.

　　4. Speed: How to make fast imaging possible? ProEM and KURO.

　　5. Imaging & Spectroscopy at the same time? And how to get accurate spectra from Near-Earth-Object / Space Debris / Satellites?

　　a. Only with aberration-free IsoPlane/FERGIE, it is feasible to put the system on the focal plane of a telescope and do both imaging/spectroscopy and get reliable results.

　　b. How we achieved aberration-free FERGIE technology.

　　6. Beyond the Visible?

　　PI offers the best scientific SWIR cameras that can be used in many interesting space/earth imaging/spectroscopy applications.

　　Ending: Future outlooks and invite for more cooperation; Star of Astronomy video

　　Last, talk about new opportunities and needed technologies in this field and how PI is going to develop new products to keep giving momentum to scientific research in Space/Earth Imaging/spectroscopy. End the speech with a Star of Astronomy video featuring cooperation in astronomy field in China.
