Part 4/10:
The process begins with an aperture that acts like a small window through which light enters. By strategically changing the angle of a mirror, the camera can capture light from different portions of the wall at different times. Each signal emitted from the laser, which flickers on and off rapidly, is recorded by the light sensor. This intricately designed system allows the camera to dynamically capture the propagation of light across a space with astounding precision.
Every captured frame consists of light intensity data over time, providing vital information about the light’s journey across the garage. But capturing this data is not without its challenges—getting a light source that can turn on within nanoseconds is crucial to ensure accurate representation.
