ברכות לאורן כהן ולקבוצת המחקר על זכייה במענק מטעם מועצת המחקר של האיחוד האירופי (ERC).
ה- ERC מממן פרויקטים בעלי סיכון גבוה של קבוצות מחקר מובילות.
Oren’s group works on ultrahigh-speed nanometer-scale microscopy. To date, we are very much blind to non-repeatable phenomena with nanometer and picosecond-scales because they are too fast and their details are too small for our imaging technology. As a result, such processes, e.g. femto-magnetism and mode-locking of micro-lasers, are still not well understood. Within the ERC project, the team aims to develop a microscopes for filming movies of non-repeatable phenomena with nanometer-picosecond scales.
The microscope is based on a new concept that the group developed, which is called TIMP – Time-Resolved Imaging by Multiplexed Ptychography (ptychography stands for folded photography). In TIMP, a dynamical object is illuminated by a burst of ultrashort pulses (with THz repetition rate) - each pulse probes the object at a different time. The interaction of each pulse with the object leads to a diffraction pattern on the CCD, yet the CCD is too slow to record the multiple diffraction patterns. Instead, it recods the sum of the diffraction patterns within a single exposure. Finally, the movie is reconstructed algorithmically from the multiplexed recorded data. The group will develop TIMP microscopes using visible and x-ray radiation as well as electrons. Excellent graduate and undergraduate students are welcome to participate in this effort.
אנו מאחלים לאורן ולקבוצה הצלחה במחקר!
