When I read "line scan camera" I thought of "rolling shutter" which in digital cameras works out to be a horizontal line at a time, which causes interesting artifacts with quick moving objects like propellers or windshield wipers. Questions that came to mind and answers as far as I can tell: Q: Are the scan lines parallel to the plane of completion? A: There is only one scan line and it is parallel to the plane of completion. "In track, the cameras are only focused on the 5 mm near the finish line." [0] Q: If yes, is the sequence of lines scanned in the same direction as the competitor movement? A: There is only one scan line. 0. https://www.axios.com/2024/08/05/noah-lyles-wins-gold-track-camera-omega https://www.axios.com/2024/08/05/noah-lyles-wins-gold-track-...
