An aircraft flying at super sonic speeds create sonic booms and light that leave behind it. Now scientists have made the ultrafast camera that can captures these ultra sonic lights. The scientists believe that the technology used behind it can be used help them to observe neurons fire and live activities in the brain.
Science and Tech
How Sonic Booms are created? Object moving in the air pushes the air in its way thus creating waves that move with the speed of sound in all directions. When a object moves with a speed of sound or greater than the speed of sound it can leave behind the pressure waves and these waves keep on piling upon one another providing us new waves known as Sonic Booms. These sonic booms produced are confined in a conical region also known as Mach Cones
Light travels at a speed of 300,000 km/s when it travels through vacuum and according to Albert Einstein, nothing can travel faster than speed of light but however the light can itself decrease its velocity when it travels through different medium. e.g When light travels through water it travels with a speed of 60% of its max value. This study has helped scientists to generate Super Sonic cones or Mach Cones. Scientists experimented it at very low scale and found surprising results with elusive scattering of light.
Ultrafast Camera
In order to capture this scattering of light, researchers developed a camera that can capture images at 100 billion Frames Per Second. The camera basically uses two things one to capture the images and the other one is to store the temporal information that would help scientists to reconstruct the event frame by frame.
The speciality about this camera is that it can capture a huge amount of information even in a single exposure. It is very helpful in analysing the unique and random events. According to some great scientists this camera have its great uses in biomedical industry to have a deep study of tissues, blood flow and even movements of neurons. This amazing camera can greatly help scientists to really know about how actually the brain works. The possibilities are limitless with this great tech.
