Neuromorphic cameras are revolutionizing the field of astronomy with their ability to mimic human eyesight and capture both extremely bright and dim objects in the same image. These cameras, also known as event cameras, operate by only recording data from pixels that detect a change in brightness, similar to how the human eye processes visual information.

One of the key advantages of neuromorphic cameras is their ability to capture high-speed movements without motion blur, making them ideal for tracking fast-moving objects in space. Traditional digital cameras sample all pixels multiple times per second, whereas neuromorphic cameras only record changing pixels, resulting in less data storage and higher frame rates.

Researchers at the Indian Institute of Science, Bengaluru, led by Chetan Singh Thakur, have demonstrated the potential of neuromorphic cameras in astronomy by installing them on telescopes to capture phenomena such as meteorites passing between Earth and the moon and images of binary star systems like Sirius A and Sirius B.

Sirius A, the brightest star in the night sky, is approximately 10,000 times brighter than Sirius B, making it challenging to capture both stars clearly in a single image using traditional sensors. Neuromorphic cameras excel at distinguishing between extremely bright and dim objects in the same frame.

Furthermore, these cameras are highly efficient at detecting fast-moving objects, offering astronomers a new tool to study celestial events with precision. By accurately tracking the movement of objects without blurring the background, neuromorphic cameras provide a unique perspective on astronomical phenomena.

While neuromorphic cameras offer distinct advantages for certain applications, they may not replace traditional sensors entirely due to lower resolution and slightly lower photon detection efficiency. However, their ability to capture dynamic events with clarity and precision makes them a valuable addition to astronomers’ observational tools.

Overall, neuromorphic cameras represent a promising innovation in astronomical imaging, enabling researchers to explore the cosmos with unprecedented detail and speed.
