Brian Haidet, a prominent creator on his **AlphaPhoenix** channel, has achieved a remarkable milestone by filming a laser beam at an astonishing **2 billion frames per second**. This innovative experiment, though recorded as a one-pixel video, showcases a groundbreaking approach to visualizing light phenomena.
To accomplish this feat, Haidet completely overhauled his previous setup. In **December 2022**, he had already developed a camera capable of recording at **1 billion frames per second**. This time, he enhanced the entire system, upgrading the motors, hardware, oscilloscope, signaling, recording software, and processing software. The result is a significantly improved resolution and a unique visual experience.
One of the most intriguing outcomes from this new setup is the way light appears to behave differently based on its direction. The footage reveals that light seems to travel noticeably faster when it approaches the camera compared to when it recedes. This phenomenon occurs due to the mechanics of the experiment: laser beams reflecting off fog particles closer to the camera arrive sooner than those bouncing back from further away. This observation serves as a fascinating visualization of **special relativity** in action, all taking place within Haidet’s garage.
The experiment not only highlights Haidet’s technical prowess but also invites viewers to engage with complex scientific concepts in an accessible manner. For those interested in the intricacies of this project, Haidet has provided additional material that delves deeper into the processes behind his groundbreaking work.
