For all the Photographers and camera lovers, Scientists have developed world’s fastest camera, which can capture 10 trillion frames per second and making it possible to ‘freeze time’ to see light in extremely slow motion. The advance may offer insight into as-yet undetectable secrets of the interactions between light and matter, according to scientists from California Institute of Technology in the US.
The study was published on October 11, in the journal ‘Light: Science & Applications’ showed that the new system based on a femtosecond streak camera incorporated a data acquisition type used in applications such as tomography.
T-CUP Camera :¬†Setting the world record for real-time imaging speed, the camera called T-CUP (compressed ultrafast photography) can power a new generation of microscopes for biomedical, materials science, and other applications.
‚Ä¢ The camera represents a fundamental shift, making it possible to analyse interactions between light and matter at an unparalleled temporal resolution
‚Ä¢ The ultrafast camera broke new ground by capturing the temporal focusing of a single femtosecond laser pulse in real time
‚Ä¢ This process was recorded in 25 frames taken at an interval of 400 femtoseconds and detailed the light pulse’s shape, intensity, and angle of inclination
Compressed ultrafast photography :¬†In recent years, the junction between innovations in non-linear optics and imaging has opened the door for new and highly efficient methods for microscopic analysis of dynamic phenomena in biology and physics. However, harnessing the potential of these methods requires a way to record images in real time at a very short temporal resolution in a single exposure.
Using current imaging techniques, measurements taken with ultrashort laser pulses must be repeated many times, which is appropriate for some types of inert samples, but impossible for other more fragile ones.
A laser-engraved glass can tolerate only a single laser pulse, leaving less than a picosecond to capture the results. In such a case, the imaging technique must be able to capture the entire process in real time.
Compressed ultrafast photography (CUP) was a good starting point. At 100 billion frames per second, this method approached but did not meet, the specifications required to integrate femtosecond lasers.
