I built an STM a while back for fun and when people ask me how I managed to "image" atoms I usually use the analogy of the STM being like a "microscope sonar" where the atoms are "blips" on a plane (the sonar map). Sure it's not actual EM radiation landing on a CMOS detector but it's still pretty neat nonetheless.
