In a remarkable demonstration of high-speed photography, Brian Haidet showcased a laser beam recorded at an astonishing rate of 2 billion frames per second on his AlphaPhoenix channel. However, there is an important caveat: the video is limited to a resolution of just one pixel by one pixel. To create a fuller image, Haidet repeats this single pixel footage multiple times, resulting in an engaging visual experience.
For this innovative project, Haidet completely redesigned his apparatus. Last December, he had already developed a camera capable of capturing video at 1 billion frames per second. This time, he enhanced the system to achieve 2 billion frames per second while also improving the resolution. This involved significant upgrades to the motors, hardware, oscilloscope, signal processing, recording software, and processing software, essentially revamping every aspect of the setup.
One of the most intriguing phenomena observed during this experiment is the apparent difference in the speed of light as it approaches the camera compared to when it moves away. This effect is a result of the experimental setup: laser beams reflecting off fog particles closer to the lens arrive sooner than those bouncing back from more distant particles. In essence, this visual representation illustrates an aspect of special relativity within the confines of Haidet”s garage.
For those interested in delving deeper into the mechanics of this groundbreaking experiment, additional materials are available, providing further insights into Haidet”s process and findings.
