A group of scientists have developed World’s fastest camera which can capture ten trillion frames per second. With this innovation it will be possible to “freeze time” to see light in extremely slow motion.
According to the scientists of California Institute of Technology, the innovation may gives understanding into the undetectable connection between light and matter. The innovations in non-linear optics and imaging has paved way for new and efficient methods for microscopic analysis of dynamic phenomena in biology and physics. But to tackle the potential of these methods requires a way to record images in real time at a very short temporal resolution- in a single exposure.
The measurements taken with ultrashort laser pulses must be repeated many times, which is suitable for some types of inert samples, but not possible for other more fragile ones. So, there must be a imaging technique that must be able to capture the entire process in real time.
Compressed Ultrafast Photography (CUP) did not meet the specifications required to integrate femtosecond lasers. To improve the concept, a new T-CUP system was developed based on a femtosecond streak camera that also includes a data acquisition type used in applications like tomography.
“We knew that by using only a femtosecond streak camera, the image quality would be limited, so to improve this, we added another camera that acquires a static image. Combined with the image acquired by the femtosecond streak camera, we can use what is called a Radon transformation to obtain high-quality images while recording ten trillion frames per second,” said Lihong Wang, Director of Caltech Optical Imaging Laboratory (COIL).
The new camera has set a world record for real time imaging speed, the camera called T-CUP can power a new generation of microscopes for biomedical, materials science and other applications.
“It’s an achievement in itself, but we already see possibilities for increasing the speed to up to one quadrillion frames per second!” said Jinyang Liang, who was an engineer in COIL when the research was conducted.
