The Technology
Time-resolved Imaging by Multiplexed Ptychography (TIMP) represents a significant breakthrough in ultrahigh-speed imaging, enabling the capture of dynamic, non-repetitive, ultrafast events. Unlike conventional ptychography, which is limited by slow scanning, or other high-speed imaging methods that often compromise resolution or full data, TIMP reconstructs multiple frames of a complex-valued object (both amplitude and phase) from data recorded in a single camera snapshot. This is achieved by illuminating a single-shot ptychography (SSP) system with a burst of mutually orthogonal ultrashort pulses and employing a multi-state ptychographic algorithm (MsPA) for reconstruction.
A key advantage of TIMP is the decoupling of frame rate from spatial resolution. The frame rate and temporal resolution are determined by the light source (the pulse burst characteristics), not by the detector’s limitations, allowing for high spatial resolution even at very high frame rates. TIMP’s system uses relatively simple optical elements, making it versatile and adaptable across the entire electromagnetic spectrum, including extreme UV and x-ray regions, with the potential for nanometric resolution. Experimental demonstrations have successfully reconstructed up to 36 complex-valued frames from a single camera snapshot, and more recently, demonstrated the ability to capture dynamics on the femtosecond scale.
TIMP opens exciting possibilities for fundamental scientific research (e.g., plasma physics, chemistry, phononics, spintronics, fluid dynamics), life sciences (such as live cell imaging and magnetic imaging, where complex-valued information is crucial), as well as for technological developments and industrial process monitoring. Its unique capability to capture transient, non-repetitive events with both high temporal and spatial resolution marks a significant advancement in understanding natural phenomena and driving technological progress
