Polariscope is an optical device used to view objects that are located at a
distance. They were invented in the early 1800s, and remained an important
instrument for astronomers until the 20th century. The optical principles used
were similar to the pinhole camera; however, a polariscope had the advantage that
it did not have to include a lens or mirror to focus the light onto the screen.
