TORONTO, Ontario – Scientists in Toronto, Canada, have achieved a remarkable feat in the world of imaging technology with the creation of a groundbreaking new scientific camera. This state-of-the-art camera, known as SCARF (swept-coded aperture real-time femtophotography), boasts an impressive encoding rate of 156.3 terahertz (THz) to individual pixels, equivalent to an astounding 156.3 trillion frames per second.
The research team, led by Professor Jinyang Liang of Institut national de la recherche scientifique (INRS), has made significant strides in ultrafast photography. SCARF has already captured ultrafast events such as absorption in a semiconductor and the demagnetization of a metal alloy, showcasing its immense potential in various fields, from shock wave mechanics to medical advancements.
Unlike traditional ultrafast cameras that capture frames sequentially, SCARF utilizes a unique imaging modality that allows for ultrafast sweeping of a static coded aperture, enabling the camera to achieve high encoding rates and capture rapid phenomena that were previously difficult to observe. This innovative approach sets SCARF apart from existing technologies and paves the way for new possibilities in scientific research.
Moreover, SCARF’s ability to capture chirped laser pulses at an unprecedented rate of 156.3 trillion times per second is made possible by its computational imaging modality, which processes spatial data in a distinct manner. The camera’s utilization of off-the-shelf and passive optical components also contributes to its cost-effectiveness and efficiency compared to other techniques.
While SCARF is primarily geared towards research applications, collaborations with companies like Axis Photonique and Few-Cycle indicate a potential for commercial development in the future. By working with industry partners, the research team aims to bring SCARF’s cutting-edge technology to a wider audience, fostering innovation and advancement in the field of imaging technology.
