One embodiment relates to a method of real-time three-dimensional electron beam imaging of a substrate surface. A primary electron beam is scanned over the substrate surface causing electrons to be emitted therefrom. The emitted electrons are simultaneously detection using a plurality of at least two off-axis sensors so as to generate a plurality of image data frames, each image data frame being due to electrons emitted from the substrate surface at a different view angle. The plurality of image data frames are automatically processed to generate a three-dimensional representation of the substrate surface. Multiple views of the three-dimensional representation are then displayed. Other embodiments, aspects and features are also disclosed.
