The ability to capture events in a trillionth of a second opens doors to significant advancements in the manufacturing of efficient electronics and clean energy.

Researchers from East China Normal University have developed a revolutionary imaging method capable of capturing events that occur in a trillionth of a second.

The new technique, called CST-CMFI (compressed spectral-temporal coherent modulation femtosecond imaging), allows for the observation of ultrafast phenomena with unprecedented clarity. This advancement enables scientists to film previously invisible processes, such as the movement of electrons and plasma formation in real time.

Unlike previous technologies that only recorded changes in brightness, this innovation can capture changes in the internal structure of objects.

How the ultrafast capture technology works

The system uses a special laser pulse that links different wavelengths to specific moments in time. When this pulse interacts with an event that lasts only a trillionth of a second, the scattered light carries detailed spatial and spectral information.

This data is compressed into a single image and subsequently processed by a physics-informed neural network to reconstruct the scene.

The final result of the processing is a sequence of frames that forms an ultrafast movie, captured in a single shot. This ability to transform transient phenomena into detailed videos allows for the analysis of the complete evolution of chemical reactions that rearrange atoms at extreme speeds.

The technique combines time-resolved spectral mapping with coherent modulation imaging, preserving fine details that would be lost in traditional methods.

Practical applications and the future of materials science

During testing, scientists used the method to observe plasma formation in water after a femtosecond laser shot. Understanding this process in a trillionth of a second could enhance laser-based medical procedures and advanced manufacturing technologies.

The team also studied the dynamics of charge carriers in zinc selenide (ZnSe), which is essential for the development of faster and more efficient electronics.

The sensitivity of phase measurements revealed subtle variations even when there were no significant changes in light intensity. In the future, researchers plan to apply the technology to study phase transitions and interface dynamics in semiconductor materials.

Additionally, the group intends to integrate the CST-CMFI with compressive ultrafast photography to separate temporal and spectral information, further expanding the possibilities of using this revolutionary camera.
