WebWith adaptive cruise control, your car uses radar and laser sensors to detect the speed of vehicles ahead and then adjusts your own speed accordingly to keep a safe distance. So, if the car in front of you slows down, your car will too. Once they’re out of the way, your adaptive cruise control will accelerate back to the speed you previously set. WebMar 2, 2024 · To make this happen, a laser beam is split into two beams that pass through lenses to expand them. One beam (the reference beam) is directed onto high-contrast film. The other beam is aimed at the object (the object beam). Light from the object beam gets scattered by the hologram's subject. desktop stretched on screen
