Scanning laser beam signals from raster-scanning RGB projectors were measured in time domain using high-speed photodiodes and a real-time oscilloscope. Temporal signal variations around 1 ns were obtained in each flame at 60 fps. These are useful for characterizing smart laser projectors from both technical and standardization point of views.
