Which two microscopes generate three-dimensional images?

A scanning electron microscope (SEM) scans a specimen’s surface and produces an image with a three-dimensional appearance. A scanning tunneling microscope (STM) maps surface height at very small scales, creating a three-dimensional topographic image. A transmission electron microscope mainly shows a two-dimensional image through a thin specimen, so the correct choice is scanning electron microscope and scanning tunneling microscope.
