movement increases, single lines of the
image remain just long enough to combine
with the others to form a recognizable
image. In this manner, the rapidly moving
rod simulates the CCD and the eye/brain
interaction simulates the final imaging
computer that receives the radioed data and
reassembles it for use.

For Further Research:
- How do television studios create and
transmit pictures to home receivers?
- How does a CCD work?
- Project some of the slides contained in the
Astrophysics Division Slide Set described
on page 82 of this guide. Magnify them
as much as possible on a projection
screen to see how the complete image
consists of many discrete parts.
