Definition of projector for English Language Learners. : a machine that projects a movie or picture onto a screen.
An overhead projector is a good example of such a tool. Draw a groundhog on a piece of paper and cut it out. Place it on the overhead projector, so that its shadow is cast onto a screen at the front of the room. Now measure your cutout and then measure the image on the screen.
