Yogeshwar Nath Mishra, a young scientist, had a difficult time travelling from Azamgarh in Uttar Pradesh to California. His farmer father gave up a lot to help him realise his goals. The battle, however, was fruitful because Mishra is now a member of a NASA and Caltech team that developed the fastest laser sheet imaging technique in the world, which is useful for studying nanoparticles in flames.
A brief about World’s fastest laser sheet imaging tech to capture combustion has been developed by a Scientist from Uttar Pradesh village
Mishra, a scientist at NASA-Jet Propulsion Laboratory at Caltech, said to indianexpress that “I was enthralled by the realm of science from a young age. I was greatly impressed by the late APJ Abdul Kalam, an aerospace scientist and a former Indian president.
Over the years, significant problems that have affected both people and the earth have been addressed thanks to scientific advancements. Mishra has accomplished something that has the potential to fundamentally alter our knowledge of combustion.
When it comes to taking pictures, standard cameras can do it at a rate of 30 frames per second. 12.5 billion frames per second have been attained. We work on laser sheet imaging, which differs from previous systems in that they only project images that are in the line of sight via a laser beam, so limiting the region. It effectively provides two-dimensional information about a plane, according to Mishra, whose work was published in Nature Light Science & Applied, a peer-reviewed magazine.
To provide details on a particular item segment, the researchers cut a light sheet through a three-dimensional object. Mishra claims that the innovation is the fastest camera for planar imaging. The maximum frame rate for contemporary ultra-fast cameras used for comparable imaging is one million frames per second. The team’s most recent innovation combines streak camera with compressed sensing technology.
“One can only observe the light’s source and destination; it is impossible to track the light’s movement in real time. But, you can observe light in action with this camera. essentially how light moves through a substance or medium. And all of this is made possible by the 12.5 billion frame-per-second speed, added Mishra, who also mentioned how they merged streak technology with compressed sensing algorithm to create a single-shot, two-dimensional camera.
Mishra, whose research focuses on laser spectroscopy, light-matter interaction, and sustainable technologies, thinks that studies on combustion can benefit greatly from the new imaging technology. The researcher claims that the process of burning results in the creation of several chemical species from hydrocarbons. Similar to how flying an aeroplane or launching a rocket causes the combustion of hydrocarbons, understanding the phenomenon is crucial.
